Fear of becoming pregnant again?


Hello, doctor.
I had sexual intercourse with my boyfriend on March 15th (and took emergency contraception), and then we had intercourse again on March 24th (with a condom).
My period started on March 26th.
I have been pregnant before and am concerned about the possibility of becoming pregnant again, so I came here to ask the doctor if there is a chance of pregnancy in this situation.
Thank you.

Dear Liang Xiao Qi,
If menstruation occurs normally after sexual intercourse, the likelihood of pregnancy is relatively low.
It is recommended to use dual contraception methods, such as taking oral contraceptives and using condoms simultaneously.
If you have any other questions, please consult a gynecologist.

More Info


When it comes to concerns about unplanned pregnancy following recent sexual encounters, it's important to consider several factors, including the timing of intercourse, contraceptive methods used, and individual menstrual cycles. Based on the information you've provided, let's break down your situation.

You mentioned that you had sexual intercourse on March 15 and took emergency contraception (commonly referred to as the "morning-after pill") afterward. Emergency contraception is most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours, but it can be taken up to 5 days after. The effectiveness decreases the longer you wait, but it can still significantly reduce the risk of pregnancy if taken within that timeframe.
Following that, you had another sexual encounter on March 24, during which you used a condom. Condoms are a reliable form of contraception when used correctly, providing a barrier that prevents sperm from reaching the egg. If the condom did not break or slip during intercourse, the risk of pregnancy from that encounter is quite low.

You also noted that your period started on March 26. This is a crucial piece of information. If you had a regular menstrual cycle, the onset of your period typically indicates that you are not pregnant. The menstrual cycle is generally divided into phases, and ovulation (the release of an egg) usually occurs around the midpoint of the cycle. If you had your period shortly after the sexual encounters, it is likely that you were not pregnant from either encounter.

However, it's important to remember that no contraceptive method is 100% effective. While emergency contraception and condoms significantly reduce the risk of pregnancy, there is still a small chance of failure. If you have concerns about potential pregnancy, it may be beneficial to take a home pregnancy test if your next period is late or if you experience any unusual symptoms.

In summary, based on the timeline you've provided—having taken emergency contraception after the first encounter, using a condom during the second encounter, and then getting your period shortly after—your risk of unplanned pregnancy appears to be low. However, if you remain anxious about the possibility of pregnancy, consider consulting with a healthcare provider for further reassurance and guidance. They can provide personalized advice and discuss additional contraceptive options to help you feel more secure in your reproductive health moving forward.
