So around 5 weeks ago, almost 6, I was with boyfreind but didn't go further than makingout, so already there was no sex and we were fully clothed. My worry is touching precum that went through his jeans and then i could've touched myself with it. I don't have any sources that say a similar story but im worried. In addition I bled on the 19th of april, but im not sure if it was my period or implantaion. It was bright red and only heavy for 1 day out of four, and it was a week early. This was 3 weeks after the incident. Last Friday marked a day before 5 weeks and tested negative so should I trust it and move one.I've been feeling dizzy and feel pulsing in my upper andomen so im worried about pregnancy regardless. Should I test again? Advice? :'(
