I'm on the depo birth control shot. And I'm really nauseated and starting to throw up at least once a day, super weak, constantly tired, I'm getting a purge where itd be when I was pregnant. My body is all off. My sense of smell is crazy. I've taken an at home and a blood test and both negative but something is up with my body. I'm losing weight everywhere but gaining only in the lower belly area. It looks like I'm pregnant. Its firm like in pregnancy. Its scaring me because of I am I want to get proper care for the baby but I can't if test are negative. And if I'm not I want to know what's happening. Anyone else have an experience like this? Also anyone know about cryptic pregnancies?
