Pregnancy Risks and Symptoms After Contraceptive Failure - Obstetrics and Gynecology

Understanding pregnancy risks and symptoms after contraceptive failure is a complex issue that involves various factors, including the timing of ovulation, the effectiveness of contraceptive methods, and individual physiological responses.
In your situation, you experienced a contraceptive failure when the condom broke during intercourse, although ejaculation did not occur. This is a critical point because pre-ejaculate fluid can contain sperm, which means there is still a risk of pregnancy. The emergency contraceptive pill (ECP) you took, known as "Plan B" or "levonorgestrel," is most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours. Since you took it within an hour, you maximized your chances of preventing pregnancy.

Regarding your girlfriend's menstrual cycle, she had her last period from July 8 to July 13, and with an average cycle of 28 to 33 days, ovulation typically occurs around 14 days before the next expected period. If we assume a 28-day cycle, ovulation would likely occur around July 22, while a 33-day cycle would push ovulation to around July 27. Given that you had intercourse on July 18, it is possible that sperm could survive in her reproductive tract until ovulation, which would increase the risk of pregnancy.

On July 23, your girlfriend experienced abdominal pain, which you suspect might be ovulation pain (mittelschmerz). This is a common symptom that some women experience during ovulation, characterized by a sharp pain on one side of the abdomen. The clear, stretchy cervical mucus you described is also a sign of approaching ovulation, as it helps sperm travel through the cervix.

As for the breast tenderness she is experiencing, this symptom can be associated with both early pregnancy and the premenstrual phase. Hormonal changes in the luteal phase (the time after ovulation and before menstruation) can cause breast swelling and tenderness. Therefore, while breast tenderness can indicate pregnancy, it is also a common symptom experienced before menstruation.

Regarding the timing of her next period, taking emergency contraception can lead to changes in the menstrual cycle. Some women may experience their period earlier or later than expected, and the flow may be lighter or heavier than usual. If her period does not arrive within a week of the expected date, it would be advisable for her to take a pregnancy test to confirm whether or not she is pregnant.

In summary, there is a possibility of pregnancy due to the contraceptive failure, especially given the timing of ovulation. The symptoms your girlfriend is experiencing, including abdominal pain and breast tenderness, could be related to either pregnancy or the premenstrual phase. Monitoring her menstrual cycle and taking a pregnancy test if her period is late will provide clarity. If there are any concerns or unusual symptoms, consulting with a healthcare provider is always recommended for personalized advice and care.
