Pregnant? no pos test. bleeding monthly but extremely light, like never before. stomach getting much bigger. would be 20wks. other symptoms present

Pregnant?: You state that you have not had a positive pregnancy test. Lighter flow does not indicate a pregnancy. Have you asked your provider for an ultrasound to evaluate the bloating? Symptoms of pregnancy could be other things as well. Your interests are best served by being completely evaluated by your provider as this could be something that needs to be addressed urgently.

See your FamilyDoc: It's unlikely to be pregnant w/ongoing monthly periods, even if light. It's even less likely to be pregnant after negative pregnancy tests. However, expanding abdomen is concerning & needs to be evaluated by your Family Doc. Ultrasound would be good noninvasive way to image belly w/o ionizing radiation. Don't wait any longer!
