At my ob check up the doc could not find the heart beat at 11 1/2 week into my pregnancy they said can still be to early . 2 days later I spotted lite a couple times which made me worry I went into er they did 3 ultra sounds the last one being a vaginal one short after they told me there was no heart beat that I had a spontaneous miscarrige to follow up with my ob which I did and its been 2 weeks and I have not bleed and feel light headed at times and still my doctor did nothing but hcg blood work I'm worried...

I think it's foolish and dangerous to second guess a Physician. Go back and talk to the Physician.

If you don't trust him/her, find someone else.
