I did a 4d and found out i was having my second son at 18 weeks
I was 16 weeks pregnant when i found out.
12 wks by blood confirmed at 16 w ultrasound
I think I was 18 weeks but I had to go to a specialist so during the ultrasound they told me the sex I wasn't suppose to find out from my regular doctor until 20weeks
I'll b 16 weeks 4 days when I go in for ultrasound. Will they be able to tell?
