Signs You Are Pregnant While on Birth Control

While nearly infallible in preventing pregnancy, birth control pills do fail sometimes and you may find yourself in that 1/2% pregnant. Find out the signs you are pregnant while on birth control.

Birth control pills are the most effective form of contraception for sexually active women. However, there are still cases when they are not enough to prevent pregnancy, but they influence the symptoms and lead to their misinterpretations. Many women see doctors and take various tests before finding out that their problem is not the condition they were afraid of, but an unexpected pregnancy.

Here is a list with 6 of the most common signs you are pregnant while on birth control.

Sudden mood change

If you are an emotionally stable person and you begin to experience sudden changes of mood or you have an exaggerated reaction towards a particular situation that normally does not affect you, this can be a sign that you conceived while on birth control. Mood swings are caused by the changes that occur inside your body and brain due to the increased level of certain hormones.

Delay in period

For women who have irregular periods, a delay is not a big deal, but, if your menstruation follows a strict pattern, a one week delay can be a sign of pregnancy. However, stress and depression can also justify a missing period, so it is never amiss to take a pregnancy test.

Frequent urination

If you urinate more frequently than before, without this process being influenced by any other condition you suffer from, the cause may be a recently installed pregnancy. When the egg is fixed, the uterus enlarges and poses pressure on the bladder, preventing it from storing the same amounts of urine.

Swollen breasts

One of the transformations noticeable on the first week after the egg is fertilized is that of your breasts. They get swollen, and touches become painful. The change appears as a result of the increased level of hormones, but, sometimes, it can also be a side effect of the contraceptive treatment.

Sensitive to smells

Excessive sensibility to smells can also be among the signs you are pregnant while on birth control. Not only that you get nausea or even start vomiting when you smell something unpleasant, but you can develop the same reaction to gentle, delicate smells that used to please you.

Change in diet

A sudden, involuntary change in your diet or eating program can also be a symptom of pregnancy, even if you take birth control pills. You may have a considerably greater appetite, and you may crave for foods in bizarre combinations, or you may not be able to eat certain foods or at certain hours.

    i have been taking birth control for 2 months now and i skipped a day 4 days after having sex. Now I feel like throwing up every 20 minutes. My boobs really hurt, there is a light brown discharge, I am constipated for at least three days at a time, and pee every hour to half an hour or so. I don’t know if I am pregnant. I am a teen and I have a obgyn doctor, but I don’t see her for another month, and I am not able to get a test at the moment. I need help….

    I have been on a specific brand of combined oral contraceptive pill, and haven’t had any side effects. I have been ill with a cold a about two weeks ago and used amoxicillin. about a week ago i started having breast tenderness, fatigue, dizziness and headaches, some nausea during the day no vomiting (could it be that that cold made a bit more sensitive to the hormones of the pill?

    I am currently taking the Minastrin 24 Fe. I have been on it since the beginning of May, and never missed a pill. I started my period two days early, but its been really different than my usual ones. Extremely light and kinda brown. Well, yesterday I took my first brown pill of the “sugar pills” (as my doctor calls them) and this morning my husband and I had unprotected sex. So, I’m just wondering if there’s any chance of me getting pregnant..? This is the first time I’ve ever been on the pill so I’m extremely new to all of this.
