So my boyfriend & I had sex almost a week ago & he came inside me. I’ve been on the implant for about 3 months, but a few days ago my breast started getting sore. I’m going to take a pregnancy test in a few days but should I be worried about being pregnant or is it just the effects of the nexaplon implant ? Besides that everything else is completely normal. I’m set to start my period in 9 days but lately my period has been all over the place so I don’t know if it’ll come or not but should I be worried about pregnancy or am I just being paranoid ?
