Hi! Congrats and welcome!
I was 39 when I got pregnant and turned 40 4 months into things. I'm currently 24 wks and everything looks good, is measuring right etc. Totally normal pregnancy.
If I can offer you any advice- follow your gut, stick with docs you feel comfortable with, don't let anyone scare the sh#t out of you(b/c some will try to) and do what you feel is best for YOU!
GL and a happy and healthy 9 mo's to you!
