question: I am trying to Conceive. I am currently 16 days late after my period should have come. I have had negative urine and blood tests but still feel pregannt: sore breast’s. About 3-4 weeks ago had 3-5 daya of heartburn at night. Tired. Recently been getting dizzy, and have blue veins showing up on my breast’s. Should I try to get my doctor to schedule an ultrasound to confirm that I am not pregnant (since I am not showing positive on urine or blood tests)??
