Thanks for your replies girls. I have been told that all of these dates are "accurate" as they're all 'early' in the preg (i.e. first half) but I have also read that the really early scans are the most accurate.
I think I will try to get an u/s tomorrow and then, if all looks ok I will push the induction back a few days. The doc wanted an u/s done on Friday but it was nearly 3pm and he couldn't get me in so then somehow we were talking induction on Monday. After I left I felt a little rushed. I also want to know if he thinks there is some medical reason for needing to deliver this baby sooner.
If you also ask for a fetal heart scan (cartiography/CTG) then your doc/the midwives can assess if bub is happy and healthy. It can then become a pretty good tool for negotiation! I was reading the policy for induction at the women's (it is online) and they suggest that if an expectant mother does not consent to induction by 40 +14 then they are to be offered the CTG scan every second day to ensure bub is ok. It is really in your hands, you can push for only having an induction if there is medical necessity. Good luck
I'd go with the March date because your potential 30day cycle does allow for that, and 8w ultrasounds tend to be more accurate than others because its dealing with a stage of foetal development that is very precise, where as the later ones are pretty much going by sizes. I think we have all managed to adequately establish that babies come in many different sizes.
Bronners - Ta. You've raised a good point about hospital policy - might ask what that is in relation to refusing inductions when I see or speak to the doc tomorrow.
Inertia - It makes sense that the further you move from the point of conception, the greater the variability in growth and development and the range of 'normal' just gets wider after they're born!
Kaz - I also remember my doctor advising me that the earlier 12 week scan is more accurate when determining a due date or date of conception, precisely for the the greater the variability in growth and development after this point. I am sure there would be more about this online.
The policy for induction at the royal women's is here if you are interested: Induction of Labour CPG
I have found it a very interesting read as my first bub was born 40 +14 (went into labour the day before) and I was due to attend an induction appointment on the day of my DS birth. I feel more informed about the process hospital's go through reading this info, just in case I have a long gestation with this bub too!
I spoke to the doc this morning. He said there is no clinical reason for needing to start an induction today so I'm going to spend part or most of the day down at the hossy having the fluid levels checked, CTG monitoring and (because I think I've just developed PUPPS in the last few days) a blood test to check my liver functioning. I don't have appointment times so will be waiting for them to fit me in but I don't care. I feel so much better getting more information before inducing.
I still feel a bit frustrated with myself that I didn't negotiate all of this on Friday in his rooms. I've done a lot of reading and know to question, question, question but then, on the spot I didn't and just went along with what was being suggested. Better late than never I guess
