When did you find out the gender & how?

Tiara
3.29.16 made 11 weeks and here he/she is! My next appointment is on 4.26.16. I'll 15 weeks, is that kinda long for an next appointment?? My OB should be able to tell me the gender by or around that time I go in right? Hubby is positive it's a boy, what do you think?
