Contraceptive pill issues


Hello doctor, I have been taking the 28-day oral contraceptive pill, and I currently have six active pills left.
Over the past two to three days, I have experienced mild cramping sensations about five times a day, but there has been no bleeding.
Is this a normal phenomenon indicating that my period is approaching? Can taking the contraceptive pill still cause premenstrual symptoms such as bloating, breast tenderness, and lower abdominal discomfort?

oo, 20~29 year old female. Ask Date: 2015/10/17

Dr. Lü Lizheng reply Obstetrics and Gynecology


The mild discomfort and pressure you are experiencing is a normal phenomenon that occurs before menstruation.
Taking premenstrual medication, most people do not experience premenstrual bloating, breast tenderness, or lower abdominal discomfort.
Sincerely, Dr.

More Info


When taking birth control pills, particularly the 28-day regimen, it's common to experience various pre-menstrual symptoms even while on the medication. The symptoms you describe, such as mild cramping, breast tenderness, and abdominal bloating, can indeed be normal occurrences as your body prepares for the withdrawal bleed that typically occurs during the placebo week of your pill pack.

Birth control pills work primarily by regulating hormones in your body to prevent ovulation. They contain synthetic versions of estrogen and progesterone, which help to stabilize your menstrual cycle. However, even with consistent use of the pill, some women may still experience pre-menstrual symptoms (PMS) due to hormonal fluctuations. These symptoms can include:
1. Mild Cramping: As your body prepares for menstruation, the lining of the uterus may begin to shed, leading to mild cramping sensations. This can happen even if you are on the pill, as the hormonal changes can still trigger these sensations.

2. Breast Tenderness: Hormonal changes can lead to breast swelling and tenderness. This is a common symptom of PMS and can occur while on birth control pills.

3. Abdominal Bloating: Many women report feeling bloated before their period, and this can also happen while on the pill. The hormonal fluctuations can affect fluid retention and digestion, leading to a feeling of fullness or discomfort in the abdomen.

4. Mood Swings: Hormonal changes can also affect your mood, leading to irritability or emotional fluctuations, which are common symptoms of PMS.

It's important to note that while these symptoms can be normal, they should not be severe or debilitating. If you find that your symptoms are worsening or causing significant discomfort, it may be worth discussing with your healthcare provider. They can help determine if your current birth control method is the best fit for you or if adjustments are needed.

In addition, if you experience any unusual symptoms such as heavy bleeding, severe pain, or any signs of a potential complication (like a blood clot), you should seek medical attention promptly.
In summary, experiencing mild cramping, breast tenderness, and bloating while on birth control pills can be normal as your body adjusts to the hormonal changes. However, always listen to your body and consult with your healthcare provider if you have concerns about your symptoms or if they significantly impact your quality of life.
