Hi! I've had Nexplanon since 2015. I just got my third implant installed 4 days ago (I know they last for 5yrs but I like to change mine every 3). The doctor said I needed to wait 7 days to have sex. My boyfriend and I like idiots fooled around last night. He penetrated me but there was no ejaculation because we stopped before he could get to tat point. I know that precum exists and it can contain sperm. What are the chances of me becoming pregnant? I also read that if you get Nexplanon inserted within the first five days of your period you're immediately protected. I got mine inserted on the 4th day of my period. I'm assuming there's a high chance I'm pregnant since I didn't wait enough time but I just wanted to ask and get some insight. Thanks!
