I was 16 weeks when they could tell the sex
I go next week I will be 14 weeks to find out.. its not to soon. Good luck.
We had a 3d/4d at 14 weeks and found out then
I found out at 18 weeks too, but was told the best time for a 3d/4d was between 27-30 weeks because they have body fat by then.
Depends on your doctor. They can tell you early on, but there's a chance the sex could be wrong. They usually wait until 20 weeks.
I was told at 18 weeks, most people don't know until 18-21 weeks
