My partner and I had sex a couple days after my previous period which was about a month ago with a condom and wasn’t sure if it broke or not so I took plan b just in case, I had no side effects but experienced brown discharge about a week after I took it, I was expecting my period 4 days ago but haven’t gotten it, I took a pregnancy text and it was negative, I know a period can be late but it doesn’t feel like I’m getting one at all? Is it possible I can be pregnant?
