I currently have an implant in my arm and have had it for over a year and have never gotten pregnant. Last night me and my boyfriend had sex and didn’t use a condom (we always do just in case) he finished inside and I didn’t think it was a big deal, but today I noticed the app say I’m in my fertile window and have a 33% chance of getting pregnant. I don’t know what to do or if I should be even worrying but I’m really freaking out and need some advice.
