With my first 3 pregnancies I also only had 2 u/s (one for dating and the 20 week scan).
My 4th pregnancy I had 6-8. I had the normal one for dating, then another a week later in the ER because I was bleeding/cramping, then the 20 week scan, then one at 24ish weeks by a perinatologist to check size of baby, then one at 30 weeks when my water broke prematurely to check fluid levels, and then I remember at least one more checking fluid levels a few weeks later. (The intial u/s were to check how baby was growing since DS1 was born nearly 11lbs, the later u/s were to check fluid levels due to premature rupture of membranes.)
This pregnancy, I am 16 weeks along and I have had 4. One growth scan, 2 more scans to check on a hemorrage, and then DH and I just had a Gender Reveal done. I will probably only have one more to check fluid levels and the baby's size and as long as everything progresses well I won't need anymore.
