me and my boyfriend have been together 4 years and we decided to have sex, so I had an Nexplanon implant done and a day later me and my boyfriend had sex, protected and unprotected, we didn't have unprotected sex for long at all but I'm scared he may have ejaculated, he says he hasn't because he gets a "feeling" when he's going to and pulled out straight away and after that we had sex with a condom, could I be pregnant?im only 14, but I have been in a relationship with this boy for 4 years and we felt it was right, any help?
