How to Tell if You’re Pregnant When You’re Taking Birth Control

Although birth control pills prevent you from getting pregnant, they are not 100% effective. With the slight possibility of pregnancy, find out how to tell if you're pregnant when you're taking birth control.

Although birth control pills have the role to prevent you from getting pregnant, none of these treatments are 100% effective. As a result, you can conceive even when you take your pills on a daily basis, without realizing it, so, the following information on how to tell if you’re pregnant when you’re taking birth control should come in very handy. Here is a list with the 6 most common and easy to notice symptoms. Claim Your 20 Free Pregnancy Tests – Click Here


If you feel exhausted during the day, even having enough sleep, it may be a sign that you are pregnant. As soon as the egg is fertilized and it is implanted in the uterus, the body begins to produce increased amounts of progesterone, a hormone that plays an important role during pregnancy. The process can make you feel tired and sleepy.


Nausea, manifested especially in the morning, is another sign of pregnancy, not necessarily related to the birth control pills you were taking, that appears after two weeks from the fertilization of the egg, or in the second half of the first pregnancy trimester.


Light cramps in the lower part of the abdomen is another symptom common to most lists on how to tell if you’re pregnant when you’re taking birth control pills. This symptom, also known as uterine cramps, appears when the egg is implanted in the uterus, and it is experienced in the first couple of weeks following conception.

Weight fluctuations

Unusual weight fluctuations can also indicate a pregnancy, being the result of the secretion of certain hormones in quantities greater than normal. While some women start to put on weight as soon as they conceive, others may lose some pounds in their first weeks of pregnancy.

Light bleeding

A light bleeding, called implantation bleeding, that occurs after the period may also be a sign that you conceived while taking birth control pills. This symptom is the result of the egg being attached to the lining of the uterus, and it usually happens in the first or second week after the egg is fertilized.

Rise in basal temperature

A higher than normal basal temperature is usually considered a symptom of the forthcoming ovulation. However, if the temperature remains elevated for days and even weeks after the egg is released, it is a great possibility for the fertilization to take place even under the influence of the birth control pills.

    I got my period last month June 13. It did not stop bleeding after my period was supposed to stop doc did test everything came back fine. They said it was a hormonal imbalance. They put me on birth control. It wasn’t helping stop the bleeding so they increased the birth control to two times a day. I wasn’t seeing results so I stoped taking birth control. I started taking it again a week after stopping it. I had no bleeding at night so I had sex my husband came inside. The bleeding has almost gone away I just spot know we have sex almost everyday for the past week after stopping and starting the pill again. Im having nausea and im dizzy all the time. Can I be pregnant? Im still spotting and im still in the pill. (I never had any symptoms since taking the birth control)

    If forgot one pill by 16 hrs and i took it as soon as i remember and continued on taking the pills at the regular time, and had unprotected sex that same day, is it very likely to get pregnant ? It is the first one i forget in about 4 months. It was exactly the day 13 on my pill package. that’s why i am concerned

    Hi I’m continuously taking the pill without taking the placebo. I’ve been doing that since March, but in the last month I have started having pregnancy symptoms such as nausea all the time, I’m barely able to eat without feeling sick, tired all the time, and back/ front pain. Is it possible I’m pregnant? My boyfriend and I have sex all the time while only using the pill.
