I think it just depends on your doctor. I know mine offered a gender reveal at 14 weeks I think but they can better tell whether your baby is a girl or a boy anywhere from 18 weeks and up. They do an anatomy scan at 21 weeks I think and up and that's when I found out because you can ask about it and they will tell you or most likely they will tell you anyway and insurance covers it where as the gender reveal one you have to pay for :) I hope this helps:) congratulations! :)
I found out at 14 weeks at a gender determination center and payed $50
I herd that you could check your ultra sound when your two.months I have this 2apps thats tells you everything one app tells you that you put your menstrual last period and then it will tells you the exact due date of your baby this other app tells you every detail of your baby and from 6wks till the day of your due date it tells you all the information you need:-)
I found out also about 13 or 14 weeks with the blood test :)
Thank you so much its my first and I'm freaking out
