Ok, this is gonna sound crazy!! I never have a period because I have a mirena. For about 2 weeks i have been spottin and my boobs have went up a cup size. I took a home pregnancy test and it was negative, so i let it go. But I have gained 10 pounds in the past 2 weeks, I feel weird rolling movements in my stomach, I have bad cramps, I have been having super weird carvings. I went and had a blood pregnancy test done and it was also negative... I really need help!!!!
