Mines every 4 weeks. And Im 17 weeks my next appointment is on the 28th of this month.

Mine is like every 3 weeks :/ and I thought that was pretty long

Yep. You usually have one at 8 weeks, 10ish weeks and then it is monthly after that until you are around 30-33 weeks, then it goes to every 2 weeks and then at the very end, weekly appointments

Sometimes. My appts was every 4 weeks until next week. Then I'll have a appt a week until she comes
