Is it possible to fall pregnant without a period?

Can pregnancy occur without menstruation for months? It is possible but quite unlikely. This is a solid reason to consult a gynecologist if you haven’t had a period in a while. There are both normal and abnormal causes for this phenomenon. What may prevent you from having periods? Could a woman be pregnant and unaware?

What do menstrual cycles have to do with pregnancy? And if you want to conceive, how can your doctor assist you if you are not menstruating?

Your Menstrual Cycle and Getting Pregnant

Your menstruation is the clearest indication that your reproductive system is attempting to function, and it signifies the conclusion of a menstrual period. The female reproductive system is complicated, but here’s a fast and easy description of what occurs each month (assuming you get periods).

At the beginning of your monthly cycle, certain hormones instruct your ovaries to begin egg development. The oocyte, or egg, is encapsulated inside a follicle. This follicle resembles a little bubble, and it is composed of fluid, nutrition, and an immature egg.

During the first 12 to 14 days of your cycle, the hormones encourage the follicle and egg to expand. The egg eventually achieves maturity.

In the middle of your cycle (at about day 14, though this can vary). The follicle ruptures, releasing the egg from the ovary, known as ovulation. The egg has a 12- to 24-hour lifespan.

After ovulation, during the second half of your cycle (roughly days 15 to 25), the hormone progesterone causes the lining of your uterus to prepare for a fertilised egg or embryo. The uterine lining is known as the endometrium. The endometrium will thicken and transform its physiological structure to accommodate an embryo during this phase.

The subsequent events depend on whether or not sexual activity occurred within five days after ovulation. If you have, sperm may be present in your reproductive system. Sperm may survive up to five days in the female reproductive system. Sexual activity on the actual day of ovulation and even the day following might result in pregnancy. If a sperm cell fertilises the egg, pregnancy will result.

Between seven and ten days following ovulation, an embryo will deposit itself into the uterine lining if conception occurs. This will stimulate several hormones to prepare the body for pregnancy.

Getting your period if you didn’t conceive

If you did not conceive, progesterone levels would begin to decrease. Reducing progesterone levels will ultimately cause the endometrium to disintegrate and eject itself. This is your menstrual cycle.

Assuming you have regular menstrual cycles, your body begins producing hormones to promote the following month’s ovulation as soon as the endometrium is shed. Your menstruation signifies the end of a cycle.

If you had a period, it is probable (but not certain) that you ovulated during the preceding two weeks, and Ovulation is essential for conception. If you have regular periods, you are likely ovulating on a regular basis.

Can you Ovulate Without Having a Period?

If you do not have periods, likely, you are not ovulating consistently. There are several possible causes for this (more on that below). However, this does not rule out the possibility of ovulating without a period.

As stated before, menstruation signifies the end of a cycle. If ovulation happens, but you do not get pregnant, you will have your period. But suppose you are now experiencing irregular menstrual periods. Depending on the cause of your irregular menstruation, you may have a sudden menstrual cycle.

The beginning of your period signifies the conclusion of your cycle, but there are no outward indications that your body has begun a cycle. Ovulation can occur without realising it.

You will only know you ovulated if you receive your period or, if you had sexual activity within your fertile window, you might get pregnant. You may not know you are pregnant for some time, though, since you have not been having periods. If you have not received your period, you will not be “late.”

13 Reasons for a Missed or Late Period

Why You Might Not Have Your Period

Amenorrhea is the medical word for the absence of menstrual periods. It may have several reasons.

Pregnancy & periods:

If you have had regular periods but suddenly stopped having them, you could be pregnant. This is certainly the first thing you think of when your period is late, and you have likely already done a pregnancy test.

However, what if the pregnancy test came back negative? Could you be pregnant still? Yes. It is possible to be pregnant and have a negative pregnancy test. However, it is uncommon. See your doctor for follow-up and confirmation, and unless you hear otherwise, assume that you are pregnant (avoid alcoholic drinks, for example).


Exclusive nursing may prevent the onset of menstruation. How long will you be menstruation-free during breastfeeding? It depends on how often you breastfeed and your own biology.

Hormonal contraception

Some kinds of contraception may halt menstruation. Your physician should have informed you whether this was possible while prescribing the medication.

If you want to conceive, the length of time it will take for your periods to return after you discontinue birth control varies on your biology and contraception of choice. Six months after the last dose of Depo-Provera, often known as the “birth control shot,” menstrual periods generally resume (if you received the injections for at least one year).

Different Medication

Contraception is not the only drug that may halt menstruation. Some psychiatric treatments, chemotherapy, allergy meds, and blood pressure prescriptions may also interrupt your cycles.


One of the most prevalent reasons for infertility is obesity. Obese women may suffer irregular menstrual cycles, and in certain instances, their periods may cease altogether. Weight loss may reset or control your menstrual cycle.


With obesity, excessive fat disrupts the body’s natural hormonal balance. The absence of fat in underweight individuals might also disrupt their reproductive cycle. If this is the issue, increasing your weight should reset your cycles.

Physical Activity or Low Body Fat

You may be neither overweight nor underweight as an athlete (based on body mass index). However, the fat percentage has a more significant effect on your reproductive cycle than your weight.

Athletes may have a high muscle-to-fat ratio and a low body-fat percentage. This might induce irregular or even total cessation of menstruation. An excessive activity might cause your periods to become erratic or cease altogether.

Stress & periods

Stress might lead you to miss one or two periods. However, it is very uncommon for stress alone to halt menstruation for months.

PCOS & periods

Polycystic ovary syndrome (PCOS) is a major cause of infertility in women. Period irregularity or absence is one of the main signs of PCOS.

Initial Ovarian Deficiency

Primary ovarian insufficiency (POI), often known as early ovarian failure, may result in irregular or nonexistent periods. Occasionally, a person with POI may spend months or even years without a period, just to have it resume for no apparent reason. POI was once known as “early menopause,” although this term is inaccurate. Following menopause, menstruation ceases permanently.

Hormonal Disproportion

In addition to PCOS and POI, additional hormonal diseases may induce ovulation issues. Hyperprolactinemia, thyroid imbalance, endometriosis, an underlying untreated medical condition (such as diabetes), and endometriosis may cause irregular or missed menstruation.

Uterine Issues

Structure-related issues or scarring of the uterus might cause irregular or absent menstruation. This may occur after a D&C or uterine surgery.


This is often the first concern women have when they abruptly cease having their period, despite the fact that it may be years or even decades before it really occurs. Although early menopause is conceivable, it is unlikely that menopause is the reason for your absence of periods until you are 45 or older.

If You Want to Conceive

The standard recommendation is to attempt to conceive for one year (or six months if you’re 35 or older) before undergoing a fertility assessment. However, this does not apply if you exhibit signs or symptoms of a reproductive issue, and included in this is amenorrhea.

If you do not have periods, you may be experiencing infertility. Ensure that both you and your spouse are assessed. There may be several causes for your inability to conceive, and male infertility is more prevalent than you may imagine.

Depending on the cause of your inability to ovulate and the presence of additional reproductive issues, possible treatments include a change in lifestyle, weight reduction or gain, or a switch in medication. Additionally, you may need therapy for an underlying medical issue or fertility medicines.

If You Wish to Avoid Pregnancy

If you want to avoid pregnancy, you should not depend on your absence of monthly periods as contraception. This is true regardless of a prior diagnosis of infertility (unless your doctor tells you otherwise).

As discussed before, depending on the cause of your missed cycles, it is possible to ovulate without first experiencing a period as a sign that you are once again viable. Discuss with your physician the best contraceptive option for you.
