I went to the ER the other day for abdominal pain, Urine pregnancy test was negative, Blood test Showed a Quantative Hormone Hcg Level of 47.5. I feel is sort of low, I Don't Have my first appointment Until Tuesday, the only Symptom that I've had so far is Fatigue and What I now know of as Implantation bleeding, I'm Scared, Should I be worried?
