Early Ovulation: How & Why It Can Impact Conception

People have several questions about early ovulation: can you ovulate early? How early can you ovulate? What causes early ovulation? Is early ovulation a health issue? Will it impact my ability to conceive?

Early ovulation can potentially cause problems if you are trying to conceive. In this article, we cover frequently asking questions about the impact of early ovulation on your cycle and your chances of conception.

Understanding Early Ovulation Symptoms

Early ovulation can be a complex phenomenon, and recognising its symptoms is crucial for those actively trying to conceive or simply monitoring their reproductive health. Here’s an in-depth look at the specific symptoms that may indicate early ovulation:

Breast Tenderness: Hormonal fluctuations during early ovulation can increase breast sensitivity or tenderness. This can be a subtle sign, so paying close attention to changes in your body is essential.

Change in Libido: Some women may experience a noticeable increase or decrease in sexual desire during early ovulation. This change in libido can be linked to the body’s natural response to fertility cues.

Basal Body Temperature (BBT) Shift: Monitoring your BBT can provide valuable insights into your ovulation patterns. A sudden rise in BBT may indicate that ovulation has occurred earlier than usual. Utilising a BBT thermometer and tracking your temperature daily can help you detect this shift.

Alteration in Cervical Discharge: The consistency and appearance of cervical mucus can change during early ovulation. You may notice a clear, slippery, and egg-white-like discharge, signalling that ovulation is occurring or about to occur.

Mood Swings: Hormonal changes during the ovulatory phase can also affect mood. Some women report feeling more emotional or irritable during this time.

Spotting: Though less common, light spotting can sometimes signify early ovulation. This is due to the sudden drop in estrogen that occurs just before the egg is released.

Abdominal Pain or Cramping: Mild cramping or a twinge of pain on one side of the lower abdomen can occur during ovulation. This sensation, Mittelschmerz, may be more pronounced if ovulation occurs earlier in the cycle.

Menstrual Cycle Variability: Understanding Ovulation Timing

If we consider a typical 28-day menstrual cycle, ovulation occurs roughly in the middle of the cycle, around day 14. According to most fertility experts, the fertility window falls in this period. That being said, the time frame is not precise for many people. In reality, ovulation happens anytime between days 12-16 of the menstrual cycle.

No two women have the same menstrual cycle — what can be considered ‘typical’ ranges from 21 to 35 days. With that in mind, you can expect ovulation to occur anywhere between the 11th and 21st days of your cycle, and what could be considered the ‘fertility window‘ will vary accordingly.

A menstrual cycle lasting 21 days or less is considered short and uncommon among women. Many factors can potentially shorten your menstrual cycle, including:

  • Mental stress
  • Illness, such as flu
  • Fluctuation in your weight within a relatively short time
  • Changes in hormonal levels and hormone medications
  • Fibroids in the uterus

One of the more critical factors, however, is your age. Women undergoing perimenopause tend to experience shorter and more irregular cycles until menopause is reached.

Pay close attention to when ovulation happens, especially when experiencing shorter cycles.

Ovulatory Phase of Your Cycle

Many signs indicate that you are in the ovulatory phase of your cycle. Alongside physical symptoms, countless methods and products are available to help you determine your peak fertility window, from daily basal temperature measurement to ovulation predictor kits (OPKs).

Basal body temperature (BBT) measurement is one of the simplest methods to determine your fertility window. During the peak fertility period, your basal body temperature can increase by 0.4 degrees over 48 hours. If you keep track of your BBT, you can make an educated guess regarding the best time to conceive.

If you happen to ovulate before day 11 of your menstrual cycle, it indicates that you have a short cycle, which might affect your chances of conception.

Conception & Early Ovulation

The time from the first day of your period to ovulation is called the follicular phase. Following this phase, your ovary releases an egg, and this phase is called the ovulation phase. The last phase of the menstrual cycle is the luteal phase.

One of the most common causes of early ovulation is a shorter follicular phase, which can cause problems regarding conception.

Let’s try to understand this by looking at the events leading up to ovulation.

The menstrual cycle begins when the endometrium lining of your uterus starts to shed, and you begin menstruating. While this occurs across approximately four to five days, a hormone called Follicle Stimulating Hormone (FSH) stimulates a few follicles (about 5-20) in the ovary. Out of these, one follicle attains dominance around the 7-day mark, and the rest die. The dominant follicle then develops further and starts to prepare itself to release an egg while simultaneously releasing another hormone called oestrogen.

Oestrogen Peak Concentration

Oestrogen reaches peak concentration in your blood during the second week of the menstrual cycle. It is a powerful hormone that prepares your uterus to receive the embryo. At the same time, the uterine mucous changes in consistency to protect the sperm and let it travel to the egg.

Oestrogen is also the hormone that rebuilds the endometrium lining of the uterus. A well-developed endometrial lining is crucial for the embedding of the embryo and its proper development.

Problems Associated With Early Ovulation

One of the most obvious effects of early ovulation is that the dominant follicle might not have enough time to develop an egg. An underdeveloped egg has a significantly lower chance of fertilisation.

Another problem with early ovulation can be the lack of ‘fertile mucous‘ formed in the uterus, which can hamper the journey of the sperm to the egg from the vagina through the uterus to the fallopian tubes. Fertility lubricants can help replicate your natural vaginal lubricants to help prolong sperm mobility and motility, bettering the chance of conception and making it a fantastic option for couples trying to conceive naturally.

Furthermore, the endometrial lining of the uterus, which is crucial for the embedding of the embryo, might not get a chance to develop during early ovulation fully. As a result, the chances of a miscarriage can be significantly elevated.

If you believe you suffer from early ovulation, there’s no need to panic. Plenty of options exist to help increase your chances of conceiving.

Treatment of Early Ovulation

If you suspect you have early ovulation, the first thing you should do is keep track of your cycle. This tracking must occur over several months until you start recognising a pattern (or have the data to back up that no pattern exists).

If you keep track of your periods, here are some possible things you might notice:

Irregular Periods

Irregular cycles are quite common among women. Certain medical conditions and stress are the most common culprits, but irregular periods often have no rhyme or reason. In many cases, these issues resolve quite easily with medical intervention.


If ovulation does not occur during a menstrual cycle, it is called an anovulatory cycle. As no egg is released from the ovary, conceiving during such a cycle is impossible. Women with shorter menstrual cycles have a higher risk of anovulatory cycles.

Anovulation can be a major reason for infertility in many women. If you believe you are suffering from this issue, you should ask your healthcare professional for tailored advice. Some strategies, like changing your diet, may help, but many factors can contribute to anovulation, and it’s certainly not a one-size-fits-all solution.


Perimenopause symptoms can begin as early as 8-10 years ahead of actual menopause, meaning women in their late thirties and early forties are often affected. It is also quite common amongst women that have fewer eggs remaining in the ovaries, which a blood test may be able to confirm.


Many women have a predisposition to a shorter menstrual cycle. Finding out your family history and the patterns of menstrual cycles of your mother or grandmother might be helpful to determine if this is the root cause of your issues.

It is always a good idea to consult your doctor if you have a shorter menstrual cycle or experience early ovulation symptoms.
