I am now overdue by about 9 days according to my due date and was meant to be induced today but decided against it. Waiting for baby to come naturally with support from our Ob. (provided he comes by Monday 17th otherwise we have agreed to induce).

When we had our appt yesterday I had reviewed my dates from basal temperature monitoring and discovered that my due date is more like 9 May rather than 3 May. I spoke to the Ob. about it and he told us that unless there is less than five days difference in dates (even when baby is an IVF baby and they know the exact date of conception) they use the ultrasound measurements and dates derived from this to determine the due date.

I didn't want to spend my whole appt discussing why this was so can't say any more but I was surprised by this fact.
