Making a doctors appointment tomorrow to  let GP know I'm pregnant. However, I'm having such bad cramps, I've had them for the last few days before I even took the pregnancy test! Is this normal? They're so intense for a few minutes then come back and go! I've already had an early miscarriage so am extremely worried :( I never had any pain like this tho, just heavy bleeding! From what I've read online it seems to be my uterus expanding?
