Anyone else find out they have Fibroids during pregnancy?

Donna • Wife, mother, employee, student.
I had a 20 week scan and the doctor gave me the results at my 21 week appointment and said I had multiple Fibroids. The largest being 3cms.  I'm scared for how this might be effecting my baby. My baby is also measuring at the 29th percentile. Is the baby small because of the Fibroids? Will my baby be born with birth defects? There is so much info on the Internet its scaring me. Thanks for any insight anyone may have with this issue. 
My doctor is horrible and was annoid when I was asking questions. I'm currently looking for a new one.
