'Pregnancies vary by 5 weeks'
Has anyone read this article on BBC today?
Whilst I don't think I25 people are enough for the study, it is interesting and something I agree with. I've been moved forward by 6 and 4 days in my pregnancies from when I know I ov'd and am always suspicious of how many people truly go 2 weeks over their true EDD.
I think it would be much better to give people a due window rather than a due date.
