How early on in pregnancy can Dr's tell the sex of the baby?

No. They wont tell u at 14 weeks. I got 1 at 16 weeks by my doctor and she said that it was still 2 early 2 tell and didnt even bother guessing. So I schedual a 3D/4D u/s and wasnt able 2 see then altho alot of people do get 2 see the sex of the baby at 16 weeks with 3D/4D u/s it was just 2 early 4 my pregnancy. Doctors usually dont/wont tell u until u are 18-20 weeks bc thats when the scan is most accurate and the genitals are developed pretty well. Good luck and congrats! :)
