So My period are irregulars I hade diarrhea like 3 weeks ago and they last for two weeks (I don't have diarrhea anymore cause I took some medicine) but Last Tuesday (July 11) I woke up feeling how I feel when I get my period so I went to the bathroom and saw some really light pink discharge when my period was due and I thought it was my period but only lasted like some hours and i didn't get my period also the day after that I felt like nauseous and my stomach really hurt that happened for 2 days and now sometimes when I eat I feel like throwing up, we have been using the pull out method (and when he takes it out 2 second later it comes out so I don't think he finished inside and he really doubts too) I had sex once when I was ovulating which was June 20 and 24 but honestly I don't really know if that's when I ovulate because like I said my period are irregulars, last time I had sex was July 8 took three pregnancy test 1 last Friday, Saturday morning and today the three of them came back negative, and I'm really stressing myself out with this because I really don't want to be pregnant, do you guys think I'm pregnant or just stressing myself ot too much? (Please don't judge I know if I don't want to get pregnant I shouldn't have unprotected sex but we all make mistakes sometimes and now I learned my lesson because this is so frustrating) also I didn't get any symptoms I usually get when I'm going to have my period🤦🏽‍♀️
