So I've been off the IUD since December. My periods have been crazy irregular. I am almost 3 weeks late. I've been having crazy headaches (which I don't get often) feeling tired, moody and crampy. I want to test but I don't want to get my hopes up for them to come crashing down again. What are the odds I'm actually pregnant. I had a regular period last month and had sex close to ovulation day.
