Lower abdominal pain with tenderness upon palpation?


Hello, on the day of ovulation (March 22), I had unprotected anal intercourse with my boyfriend, but he did not ejaculate.
There were a few times when he accidentally slipped to the front but did not penetrate.
I took the emergency contraceptive pill within thirty minutes afterward.
My next expected period is on April 5, but I've been feeling discomfort in my lower abdomen these past few days.
Could this be the result of the emergency contraceptive pill? Was the contraception successful? Also, does feeling hungry cause discomfort in the lower abdomen?

Wishing you good health.

More Info


Understanding lower abdominal pain after unprotected intercourse can be multifaceted, particularly in the context of recent sexual activity and the use of emergency contraception. In your case, the timeline indicates that you had unprotected anal intercourse during your ovulation period, followed by the administration of emergency contraception (the "morning-after pill") shortly after the event.
Firstly, it’s important to note that the use of emergency contraception is generally effective in preventing pregnancy when taken within the recommended time frame after unprotected intercourse. Since you took the pill within 30 minutes, the likelihood of pregnancy is significantly reduced, but it is not 100% guaranteed. The hormonal changes induced by the emergency contraceptive can lead to various side effects, including abdominal discomfort, changes in menstrual cycle timing, and other gastrointestinal symptoms.

The discomfort you are experiencing in your lower abdomen could be attributed to several factors:
1. Hormonal Effects of Emergency Contraception: The hormones in emergency contraceptive pills can cause side effects such as nausea, abdominal pain, and changes in your menstrual cycle. These symptoms can occur as your body adjusts to the sudden influx of hormones.

2. Ovulation and Menstrual Cycle: Since you had intercourse during your ovulation period, your body is naturally going through hormonal changes. This can lead to sensations of discomfort or cramping in the lower abdomen, which may be mistaken for menstrual cramps.

3. Gastrointestinal Factors: If you are feeling hungry, it is possible that your abdominal discomfort could also be related to gastrointestinal issues such as gas, bloating, or hunger pangs. The stomach and intestines can sometimes cause referred pain that feels like it is coming from the lower abdomen.

4. Psychological Factors: Anxiety about potential pregnancy or the implications of unprotected intercourse can also manifest as physical symptoms, including abdominal discomfort. Stress and anxiety can lead to muscle tension and gastrointestinal disturbances.

5. Other Medical Conditions: While less likely given the context, it is important to consider other potential causes of lower abdominal pain, such as urinary tract infections, ovarian cysts, or other gynecological issues. If the pain persists or worsens, it would be prudent to consult a healthcare provider for further evaluation.

In summary, the discomfort you are experiencing could be a result of the hormonal changes from the emergency contraception, natural ovulation-related sensations, or gastrointestinal issues. If the pain continues or is accompanied by other concerning symptoms (such as severe pain, fever, or unusual discharge), it is advisable to seek medical attention to rule out any other underlying conditions.
Lastly, regarding your question about whether you are successfully avoiding pregnancy, the emergency contraceptive is likely effective, but if you experience a missed period or unusual symptoms, consider taking a pregnancy test or consulting with a healthcare provider for further guidance.
