I had unprotected sex on april 19, it started at 11:40 or 11:50 maybe and carried onto 12 and more.. my fertile window opened today april 21(according to this <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> app) and it said that april 19th my chances of pregnancy was 7% (according to this app) im not on any form of birth control..we were having sex n it came out or he took it out and clear stretchy fluid was on my thigh..i dont think any got on or in my vagina but i dont know..i thought he nutted but he said he didn't..he said he didnt pre-cum either.. i don't know if he is true because they say sometimes you can't feel it come out he said it had to have been me bc we had just started and i did feel like i had to pee..i've been thinking about getting an emergency contraceptive..should I?
