Probability of Pregnancy
On July 20, I had intercourse with my boyfriend using a condom, and he did not ejaculate.
My last menstrual period started on June 30.
What is the likelihood of pregnancy in this situation? Since it was both of our first times, I am feeling anxious.
Today (July 29), I have started to feel a dull, cramping pain in my lower abdomen, and my emotions have been unstable.
Could this be a sign that my period is coming?

More Info
When considering the chances of pregnancy after unprotected intercourse, it's essential to understand the timing of ovulation, the menstrual cycle, and the effectiveness of contraceptive methods. Based on the information you provided, you had unprotected intercourse on July 20, with your last menstrual period starting on June 30. This means your cycle is approximately 30 days long, which is relatively typical.
In a standard 28-day cycle, ovulation typically occurs around day 14. However, cycles can vary, and ovulation can occur anywhere from about 11 to 21 days after the first day of your last period. Given that your last period started on June 30, you would likely have ovulated around July 14. Since you had intercourse on July 20, this timing suggests that you were past your ovulation window, which generally decreases the likelihood of conception.
However, it is important to note that sperm can survive in the female reproductive tract for up to five days. If you had ovulated later than expected, there is still a possibility of pregnancy, albeit lower. The symptoms you are experiencing, such as abdominal discomfort and emotional changes, can be attributed to premenstrual syndrome (PMS) or the onset of your menstrual period, which typically occurs about two weeks after ovulation.
If your menstrual cycle is regular, you can expect your next period around July 30. If your period does not arrive on time, it would be advisable to take a home pregnancy test for confirmation. These tests are most accurate when taken after a missed period, as they measure the hormone hCG, which increases significantly after implantation.
If you are feeling anxious about the possibility of pregnancy, it may be helpful to consult with a healthcare provider. They can provide guidance on contraception options, discuss your menstrual cycle, and help you understand your body better. Additionally, if you are experiencing significant emotional distress or physical discomfort, it is essential to seek medical advice.
In summary, while the chances of pregnancy from the encounter on July 20 are relatively low, it is not impossible. Monitoring your menstrual cycle and being aware of your body’s signals can help you manage your reproductive health effectively. If you have further concerns or questions, please do not hesitate to reach out to a healthcare professional for personalized advice.
