Im wondering if you have the Mirena IUD if when you take a home pregnancy test if it come back positive but your test at the hospital and blood work come back negative and you take another one and it goes from positive to negative are you pregnant or what do you do? Im freaking out cause I've gained weight and I have a baby bump looking stomach I have to pee every 10 minutes and I'm always hungry, eating and craving weird things.WHAT DO I DO?
