.i had my period on august 11-15th and then had sex between the 19-26 off and on and again on the 29th -sept.2nd unprotected. today is the 6 and for the past 3 days ive been having a slight brown discharge that comes and goes but only when i wipe. its so weird i never experienced it before i am expected to get my period around the 10th or 11th of september do you think it could be a early sign of pregnancy? i have been having a change in appetite and i feel tired more often and also a little nauseated. i crave for certain things, but i took a test on the 2nd because of my nausea and slight dizziness and always get hungry. but it came out negative. ive heard that it might be still early to detect so im just waiting for my pd if i even get it. is it possible though that i could be pregnant? .
