I feel silly asking since this is my 3rd pregnancy but it has been almost 5 years so it's all gotten kind of fuzzy.

I am 17 weeks pregnant and so far I have had 3 ultrasounds ( all before i heard the baby's heartbeat) and I just heard the heartbeat for the first time at my visit last week. I am scheduled for an anatomy scan on the 23rd of this month. I have only actually seen my OB twice and they havent done any belly measurements or any tests besides the regular urine sample and a blood test at my intake appointment almost 2 months ago. I feel like I had way more testing by this point in my last 2 pregnancies. Is this normal? #myfirstpost
