Hello, based on your description, if you have had irregular menstrual cycles and did not use appropriate contraception, there is a possibility of pregnancy.
I recommend that if your period is more than a week late, you should take a urine test to check for pregnancy.
Thank you! Wishing you peace and health, Dr.

When it comes to understanding the chances of getting pregnant, it's essential to consider the timing of ovulation in relation to the menstrual cycle. In a typical 31-day cycle, ovulation generally occurs around 14 days before the start of the next menstrual period. For your girlfriend, with her last period starting on March 1, ovulation would likely occur around March 15.
Given that you had intercourse on March 26, this date falls well after the estimated ovulation window. Sperm can survive in the female reproductive tract for up to five days, but since ovulation would have already occurred by March 26, the chances of conception from that encounter are quite low.
However, it’s important to note that menstrual cycles can vary, and ovulation can sometimes occur earlier or later than expected due to various factors such as stress, illness, or hormonal changes. If your girlfriend has a consistent cycle, the likelihood of pregnancy from intercourse on March 26 is minimal, but not entirely impossible if her cycle were to vary.

In terms of contraception risks, if you are not actively trying to conceive, it is advisable to use reliable contraception methods to prevent unintended pregnancy. There are various options available, including hormonal contraceptives (like the pill, patch, or IUD), barrier methods (like condoms), and natural family planning methods. Each method has its effectiveness rates and considerations, so it’s important to choose one that fits your lifestyle and health needs.

If you and your girlfriend are considering pregnancy in the future, it may be beneficial to track her menstrual cycle and ovulation patterns more closely. There are various apps and tools available that can help with this. Additionally, consulting with a healthcare provider can provide personalized advice based on her health history and reproductive goals.

In summary, while the chances of getting pregnant from intercourse on March 26 are low given the timing of ovulation, understanding the menstrual cycle and ovulation can help you make informed decisions about family planning. If you have further concerns or questions about contraception or fertility, it’s always best to consult with a healthcare professional who can provide tailored guidance.
