0k,Again my last real period was on Feb.5.However, I took a urine test and it came out to be negative.I took the test on Apr.29th. I linked the two missed periods to stress.This month on May 5th I experienced extremely light spotting.It lasted about three days.I've continued to have unprotected sex without any form of BC.Not even withdrawal.My periods are usually from light to heavy and lasts a full week.I don't know what to think..how to feel...or what to do.Could this be implantation bleeding?Could I actually be pregnant this time?Could this be an actual period?How soon after now could I tell if Im really pregnant.
