had sex last Tuesday used a condom, it didn’t break I was suppose to get my period last Thursday but haven’t gotten it. I have a really irregular period but since Sunday I’ve been super nauseous for the majority of everyday with fatigue fever and heat flashes, no stopping no cramping no tender breasts. I’m scared I might be pregnant. I also found a vaginal inclusion cyst 3 days ago and am on antibiotics for it. Could the cyst and stress be delaying my period or is it more possible that I’m pregnant ???
