My doctor had me mail mine in between 20-24 weeks
On my papers the hospital wanted them filled out by the time I was 4 months. I never did though and have been in the hospital twice and they already had all my info from my doctor
I registered at 37 weeks only because of my insurance change.
I registered online at 26 weeks
I was given mine at 12 weeks and told to mail them 2 months before my due date
I don't think it will, I think you'll be fine.
Im going to ask on my next appointment hopefully it won't be to late
You should have asked when to fill them out. Every doctor is different. You can call tomorrow and ask :)
