I've taken several pregnancy tests they've all read positive I've had symptoms and such like swelling breasts sensitive to the touch and nausea vomiting dizzy sensitivity to hot and cold and cramping. Suddenly I'm having cramps last more than a minute and my breast don't feel swollen anymore and my stomachs was starting to get hard now it feels soft but there's no bleeding but I still have extreme hunger and cravings and nausea did I miscarry or is this normal?????
