I had a very fair to line pregnancy test just before my period. Then the day it was due I got a very heavy period. I mean heavy completely different from any heavy period I ever got. A few friends told me it could be a chemical pregnancy. I have an obgyn app Dec 2. Would he be able to tell me if it was or not? The amount of bleeding had me worried. Went from super heavy for 3 days to barely anything the last 2. Thanks.
