What is the reason for my vaginal bleeding on the same day of my very first intercourse?

Hi doctor,

I had unprotected intercourse for the first time one month ago. That day itself, bleeding started. I am not sure whether the bleeding I had was menstrual bleeding or because of the I-pill that I took. The bleeding lasted for seven days, and it was very light on the last two days. I took the pill within 26 hours of unprotected intercourse. But I did not have my periods for this month. I took a urine pregnancy test 30 days after the intercourse, and it came back negative. Is there any chance of pregnancy?

Kindly help.

Hi doctor,

I had intercourse for the first time and started bleeding instantly. I took the pill the next day after intercourse, and the bleeding continued for seven days.

Thanks.

Hi doctor,

Thanks for the reply.

I will do a blood test and revert immediately. Is there any chance that the bleeding I had was because of the pill I took? And will my periods for this month get delayed? Is the home pregnancy test result taken precisely after one month of intercourse reliable?

Kindly help.

Hi doctor,

Thanks for the response.

I am really worried, as I am not being able to ask anyone about this. After having intercourse for the first time, how many days one can bleed because of the intercourse? If the bleeding was because of the pill I took, does it confirm that I am not pregnant?

Thanks.
