So last month in march me and BoyFreind were having sex but the condom broke inside of me he pulled out and then came and me being the paranoid person I am I ask him to get me a plan b but I wasn't able to take it till two days later and a few days later I got my period and now this month in may I'm about two weeks late on my period , is there a chance I might be pregnant ? Is it a symptom of the plan b for it to make miss my period ?
