I saw my gynae at week 7. The next appointment will be at week 15. Is the interval too long?

Agree with all the mommies here, around week 11-12. Maybe check with your gynae. The main tests (FTS/NT scan, NIPT, antenatal blood test) for first trimester are done around week 10-12. By week 13 to 14, I had the test results (in 2 appointments). Now waiting for my next appointment in Week 19-20.
