I'm 17 and sexually active with my boyfriend. My period was lighter what it usually is. I also usually have a little brown discharge after my period for a day, which is normal. But It was different this time. it was brownish red and I've had it for bout 4-5 days now. I've never had it like this before. I read online that it could be from pregnancy. Is there anyway I could be pregnant? And would it be too early to take a home pregnancy test?
