Due: October 8th

Hello! Okay, so I’ve had a miscarriage a successful pregnancy, and I am currently 6 weeks 3 days pregnant. I was feeling starved and nauseous every morning and it all just stopped like it did with my miscarriage. They took an ultrasound (abdominal) at 6 weeks and we could see the gestational sac, with nothing (or so it appeared) inside. Is that because it was abdominal or is something wrong?
