I had my period from December 19-24 and I got my IUD On the 27th. I’m supposed to be in my fertile window right now, day one is today. Early this morning, my boyfriend and I had sex without a condom at first. I told him we could try it for a few seconds. He made sure there was no precum or anything. He pulled out and we got a condom and finished up. He’s worried that I could have a chance of getting pregnant but I don’t think I do. I have the Kyleena implant
