So I had sex without a condom last night and I've been on the Skyla IUD for almost a month (got it Jan 13) and their website/my doctor said it would take 7 seven days after insertion for it to start preventing pregnancy. He also pulled out, and my last menstrual cycle was Jan 28 - Feb 5. I know this is probably just me psyching myself out but there's almost no logical probable way that I could get pregnant? I know there's always that tiny tiny teeny chance but I used one and a half (I'm counting pulling out as half because it can be sketchy) but I also have the IUD.
