Hello, well I have been on loestrin 24 fe for some months now. I noticed recently that I have this light brown line on my belly. Me and me boyfriend do have unprotected sex. My last period was very light. And I haven't gotten this months period just yet. Is this light brown line normal? Should I be worried? How soon should I wait to take pregnancy test? Also, how many pills do someone need to miss in order to get pregnant?
