i got the nexplanon implant on April 24th. me and my boyfriend had sex on June 19th, with a condom,me still being on the implant, and him not finishing in me. I was supposed to get my period somewhere around the 15th, but I have not gotten it yet. I know the implant can mess with your periods or even make you not have them. I'm probably just making it all up in my head because I'm only 17 and don't want to be pregnant right now, and its really stressing me out (which can also cause my period to be late) . has this happened with anyone else? is this normal? should I take a test? should I just wait? thank you, I'm just really stressed out about this
