Okay, I have a 15 month old son. With him I knew before I missed my period or even took a test I was pregnant. After him I got the mirena IUD. So I've had it for a while, over a year. We don't use condoms but he always pulls out. We haven't had any accidents. I haven't had a period since I started this birth control. We have sex at least once a week. I'm REALLY cramping and this isn't normal for me. I've felt kinda off. I took a test but negative. Could I be pregnant again? Am I freaking myself out??
