Thanks I shall check into it all on Thursday.
I would highly recommend a 3d scan does cost you out of pocket but its amazing :)
With my first I only got one every month then when I was closer to my due date every two weeks. It just matters on your doctor. My doctor likes to keep a eye on the babies
You can ask your doctor if you can have another one done. Most places only do 1-2 but your doctor may do another one for you if you ask.
You can always pay for a 3d ultrasound. They usually don't do another after the anatomy scan.
You most likely won't have another one, if you do it won't be until 37 weeks
Alot of places normally don't do more than one ultrasound unless there is complications or unless they do a growth scan in the 3rd trimester
