so last August 26 my boyfriend and i were making out then we start heating up, then he rubbed his penis into my vagina without condom, that time i have some spottings (brown) he didn't really inserted it but he just rubbed outside of my vagina. that moment i thought i was safe that night so i didn't think much. so fast forward i don't know if i am pregnant cause my period is late in 4 days it should start this September 11 but it's already September 14, but i already take a 3 pregnancy test and they all end up negative. i don't know if my period is late because we moved in another house and i kindda push myself too hard in carrying heavy stuff and walking in a far places. i don't feel any pregnancy symptom, but i felt some noticeable cramps that i felt when my period will start but it's already a week and still my period still not coming.I don't have a lot of discharge, my discharge is thin white creamy but often i dont have discharge. am i only stressed and anxious that's why i have a late period or am i really pregnant. i've been stressing out lately cause of this problem and school works in college is killing me. and i don't have any good sleep
