Hey all I'm not really that worried anymore but wanna hear all your thoughts. So my girlfriend and I had anal sex and was first for me and I was going fast and fell out and bumped her vagina and idk if there was any precum or not. And she has irregular periods she usually cramps for a week then after that week it goes away and starts period or she just dosent have a period. And been 3 weeks since the anal and she cramped and everything like usual and got bloated and she has bad cramps. Then cramps went away and never started period this is a first for her. Cramping and not started. She's been taking a pregnancy test once a week since then and says she's negative and not pregnant. But I read can be pregnant and not show up on test. We don't want to go to doctor and get blood pregnancy test done. You all think she is safe and not pregnant? Should we be worried?
