excuse me?


If my girlfriend and I had sexual intercourse several times 4 to 5 days after her menstrual period ended, and we used condoms, but I'm concerned about the quality of the condoms, is there a chance she could get pregnant? How likely is it? Would taking one emergency contraceptive pill be effective?

Dr. Li Guanghan reply Obstetrics and Gynecology


Hello: If you used condoms (which usually contain spermicide), the chances of pregnancy are very low, especially if your period is approaching.
If you want to use birth control pills as emergency contraception, you must take five pills at once.

When considering the possibility of pregnancy after a menstrual period, it’s essential to understand the menstrual cycle and the factors that influence fertility. The menstrual cycle typically lasts about 28 days, but it can vary from person to person. Ovulation, which is when an egg is released from the ovary, usually occurs around 12 to 16 days before the start of the next period. Sperm can live inside the female reproductive tract for up to five days, which means that if you have unprotected intercourse in the days leading up to ovulation, there is a chance of becoming pregnant.

In your case, if you had sexual intercourse 4 to 5 days after your girlfriend's period ended, the likelihood of pregnancy depends on her individual cycle. If she has a shorter cycle (for example, 21 days), ovulation could occur soon after her period ends, increasing the risk of pregnancy. Conversely, if she has a longer cycle (around 35 days), the risk may be lower.
Using a condom is a reliable method of contraception when used correctly, as it can significantly reduce the risk of pregnancy and also protect against sexually transmitted infections (STIs). However, if there is a concern about the quality of the condom, such as it breaking or slipping off, this could increase the risk of pregnancy. It’s important to check the expiration date and ensure that the condom is stored properly to maintain its integrity.

Regarding the use of emergency contraception, taking a single dose of emergency contraceptive pills (commonly referred to as the "morning-after pill") can be effective if taken within 72 to 120 hours after unprotected intercourse, depending on the specific type of pill. If your girlfriend is concerned about the risk of pregnancy, she should consider consulting a healthcare provider to discuss her options, including emergency contraception.

In addition to these considerations, it’s important to note that hormonal contraceptives, such as birth control pills, can be very effective in preventing pregnancy when taken consistently and correctly. If your girlfriend is already on birth control and has been taking it as prescribed, the chances of pregnancy are significantly reduced, even if intercourse occurs shortly after her period.

In summary, while there is a possibility of pregnancy after a period, the actual risk depends on the timing of ovulation in relation to the menstrual cycle, the effectiveness of the contraception used, and whether it was used correctly. If there are any concerns about potential pregnancy or contraceptive methods, it is advisable to consult a healthcare professional for personalized advice and guidance.
