Hi Kylie33- Congrats on your great news- wishing you a H & H pregnancy.

With my DS i my date were changed 3 times and i ended up going to 43.6 weeks according to the last date they gave me. ( first one was October 20, October 31 then Nov 1st then they went back to the 2nd one Had DS Nov 16th)

This time round i had problems TTC only got AF for one day. Its hard to accurately find the EDD. But my GP estimated it as 17th May. My forst US showed i was due 25th May (was very sick with MS) went for my 12 week scan and they changed my date to 19th May. SO thats the day i'm sticking with. I'll probably be Overdue again anyways.

Good luck
