I've had the IUD in place for 3 years now, my last period was about 2 years ago. Lately I've been very tired, all I want to do is sleep. I'm craving things I don't like (which even with my first pregnancy I never did). I've been very nauseated lately. My stomach hurts so bad. My backs been killing me. I have took about 2 pregancy test and they both came out negative so I'm very confused. and I don't have health insurance to just go in for a blood test.
