Vaginal Bleeding top 10 reasons

Implantation spotting

Implantation spotting is the light spotting that occurs during the period between ovulation and the expected menstruation. 

The theory that’s often repeated online is that when a fertilized egg gets implanted into the uterine lining, the lining in that area shades slightly, causing what women notice later as light spotting. But, there is no proof that this occurs considering that an embryo is tiny, and the area attached to it will also be tiny.

While this theory may be far-fetched, it could be possible that the embryo that gets implanted into the uterine lining triggers a hormonal reaction that causes light spotting.

Women receiving fertility treatments are also likely to spot, but it is unclear if the spotting occurs due to early pregnancy.

One research found that women who take a particular kind of progesterone are more likely to spot it than those who take another form of the hormone. Although spotting occurred more in one group, pregnancy rates were still similar. In other words, the study proved that spotting was neither bad nor good.

Vaginal Bleeding & Start of a miscarriage

If you have done a pregnancy test and got a positive result, then you notice spotting, you will likely think you are having a miscarriage. However, as stated above, spotting can be a sign of early pregnancy, so seeing it after a positive pregnancy test will not mean that you are miscarrying. Almost 50% of women who get vaginal bleeding during the first trimester (3 months of pregnancy) still continue with their pregnancy. Therefore, there is a chance your pregnancy will be fine even when you experience spotting.

Most women who get spotting during pregnancy, undergo a healthy pregnancy without spotting, or experience spotting that leads to miscarriage can not distinguish between these three experiences.

Instead of driving yourself crazy due to spotting, the best thing to do is to contact your doctor. This is particularly important if you experience vaginal bleeding after testing positive for pregnancy. Your doctor will likely run some blood work, do an ultrasound or prescribe progesterone if you haven’t started taking it.

If you do not have a history of miscarriage or infertility, your healthcare provider may opt not to offer any form of treatment but recommend relaxation. The only time you will need to call your doctor again is when you experience pain or cramping, which often means things are getting worse.

Ectopic pregnancy & Vaginal Bleeding

Experiencing complications during pregnancy and also cause vaginal bleeding.  For instance, ectopic pregnancy is known for causing bleeding, and this case occurs when the fertilized egg gets implanted in the fallopian tube rather than the uterus. If you noticed other signs of ectopic pregnancy accompanied by vaginal bleeding, you should call your doctor right away.

Additional reasons for spotting

Sometimes spotting can occur due to other reasons besides pregnancy. Here are some possible causes:

Hormonal imbalance

Progesterone and estrogen are the primary hormones that regulate your menstrual cycle. If any of the hormones get out of balance, you may experience spotting. Some of the factors that cause hormonal imbalance include:

  • Thyroid gland problems
  • Dysfunctional ovaries
  • Stopping or starting birth control pills

In addition, some women experience spotting during ovulation due to hormonal changes.

Vaginal bleeding may also occur during the first three months of taking any hormonal contraceptive. These contraceptives include an intrauterine device, birth control pills, contraceptive implants or injections, or contraceptive patches.

Transvaginal ultrasound

While doing a transvaginal ultrasound, the wand may bump into the cervix leading to light spotting. What’s more, taking progesterone or fertility drugs may cause the cervix to be more sensitive, increasing the chances of spotting.

Sexual intercourse

When the cervix gets hit during sexual intercourse, it can cause light spotting, which is especially common if one takes fertility drugs.

Uterine fibroids

Uterine fibroids are non-cancerous growths that commonly form in the uterus and are prevalent in women who have given birth.

Fertility drug side effects

If you are taking fertility drugs like Clomid, you may experience spotting as a side effect. 

Gynecological procedures

Undergoing gynecological procedures such as a pap smear can lead to light spotting.

IVF or IUI procedures

Some women experience light spotting when undergoing fertility treatments like IVF or IUI.

When should you worry about Vaginal Bleeding?

While occasional spotting experienced between periods shouldn’t cause you to worry, there are times you will need to call a doctor. This includes instances such as:

Spotting before period starts or between periods – bleeding for two or more days before the expected day of your period is associated with endometriosis. Spotting may also be a sign of an infection, fibroids, hormonal imbalance, or in rare cases, cancer, so be sure to get a checkup if you experience frequent spotting between cycles.

Experiencing heavy bleeding while pregnant – whenever you start to have a flow that’s similar to your period or notice that the spotting is transitioning to heavier flows, you should call your doctor or visit a hospital.

Experiencing bleeding or spotting that’s accompanied by cramps or pelvic pain – general achiness or mind cramps may be common during early pregnancy and when having menstruation. However, bad cramps aren’t normal, so getting a checkup right away is essential. 

So if you are pregnant, having mild cramps, and spotting, you should call your doctor. This way, you will know if what you are experiencing is normal or opt to get an ultrasound and blood work. It’s always better to consult a health care provider than to assume everything is fine.

Vaginal bleeding accompanied by severe pain may be a sign of ectopic pregnancy, and if you are on fertility drugs, it could be a complication of ovarian hyperstimulation syndrome. It may also indicate that you have acute PID, so get medical attention as soon as you can.

Abnormal vaginal bleeding that’s unrelated to your menstrual cycle may be a signal of a problem
