Switching OB's

Brenda

So I went to the doctor's today and found out that they don't do an US until 20 weeks, so I don't get an early one at all to see how baby's doing or if there is more then one in there...

I've gained 10 lbs since pregnancy and I'm only 12+5. Pre pregnancy I couldn't gain weight to save my life...

I feel like there should be a scan to make sure baby is ok, how many their are, and a more accurate date...

The lady couldn't find a heart beat on the dopler, and my friend couldn't find it at home either, even though we found one on memorial weekend...

What do you guys think? Is this normal? Should I switch OB's?
