Hi I'm getting brown discharge from past two days. I had sex 3 times in this month with my boyfriend and I have taken birth control pill i.e. ipill immediately after intercourse eat could be the reason for discharge

The discharge is likely due to the ipill. It would be best to find an alternative form of birth control, including the use of a condom for your boyfriend, as the ipill is not meant to be used on a regular basis.

It is also important to remember that no form of birth control, including the ipill, will be 100% effective, so pregnancy can still be a possibility... not likely, but possible.
