Just want someone to tell me everything is going to be ok....

Went to the ER on Thursday for bleeding. Thought I was 6 weeks but may be closer to 5. The tech couldnt find anything on an ultrasound but my hCG was 520. They sent me home and sent everything to my OB. Saturday I had another blood test and my hCG was 747 and progesterone was 12.3. Dr called this morning to say that my numbers went up, but it's still too early to tell. She said it could be normal, could be a miscarriage or could be ectopic. She was so short and quick I couldn't ask any questions on the phone. Shes going to order another blood test tomorrow. My husband and I have been TTC for over a year and have watched all our friends and siblings welcome new babies....we finally get our two pink lines and every day I feel like I could lose it. None of the doctors give me anything comforting to go on...I'm just so scared. No heavy bleeding since Thursday but very light brown spotting and dull cramps. This waiting game is driving me absolutely crazy and my heart is so sad. How do you deal with the wait while your body figures whatever it is out that its going to do? I pray but I cant get my mind away from the worst outcome.
