ive taken about 3 pregnancy tests and one was positive but when. I took the third one it was negative so I didn't think anything of it. I've had mirena since April, never had a period it's December. Now I'm starting to get brown discharge like a period it started out jusr spotting but this is the first day I need to actually wear a panty liner. I've been eating a lot lately and having very mild stomach cramps on and off I wonder if I could be pregnant or what. I hate going to the doctor, wondering if anybody else has experienced this??
