Girls, hello, on August 26th I had my first appointment with a gynecologist, they put me at 7-8 weeks. The next appointment is only September 24th, it will be 12 weeks and only after the appointment will they send me for screening. Is it too early for the first screening? After all, it takes several days to submit the tests, and that's already the 13th week?!
