Hi! I'm 10 + 3 according to LMP which means I have a due date of 8 Sept. However, I have got quite long cycles (when not PG), I worked out today the average over the previous 6 months was 34 days. Does this mean my edd is likely to be put back at the dating scan? Did anyone not have their dates changed who had long cycles? Thanks!
Lots of people have their dates changed, even with a 28 day cycle. Because one woman could ovulate on day 10 and one on day 17 and both get pregnant but have babies a due a week apart.
The lmp is just a guide to care before the dating scan gives a more accurate date. And realistically, a normal pregnancy is between 37 and 42 weeks and you can't predict where they'll come in that window. I know when I ovulated and mine arrived at 37 and 38 weeks respectively.
So I guess in short, some people have their dates changed and due dates aren't accurate anyway, not in real terms.
