Im a ftm too and my due date has change 7 times, my midwife said she is going by my 13 week scan because thats when babies are at there average. So according to that im due the 18th of aug but i have been also told 20, 21, 16 and 14 lol
Oh and the 22 and 24 also haha
At my 20 weeks scan my son was measuring 4 days ahead. But due date stayed the same. He could come sooner or later. His choice! Hahaha
I too have been told multiple due dates but they told me to go by the first one since all the dates were only days apart.
