This is my second pregnancy, with my 1st I had more ultrasounds bc they just wanted to do them. This pregnancy I'm 15 weeks and don't get another ultrasound until the 20 week anatomy scan. My last was at 13 weeks. How do we know everything is ok? I haven't gained any weight, just look bloated, I don't feel anything... do the doctors go off of blood work and last ultrasound and assume I'm good without another ultrasound until 20 week?
