hmmm...

I guess it's a bit strange coming at this with the perspective of an IVF pregnancy.

I didn't really have a proper cycle to speak of - just constant bleeding while on the pill used for down regulation, so we ended up having to invent a LMP date just to keep the computer software happy.

That said, we knew the exact date, even moment of conception. None of the doctors or sonographers ever questioned that, and as soon as they were told IVF, they asked for my dates and took them over scans. Seems a bit ridiculous that they could trust IVF technology, but not a woman's opinion of her own body.

However, my OB still sent me for a dating scan. It was an excuse to get me in for a proper scan between my last appointment with her and my nuchal scan as she knew I was a major stress head and had suffered three previous miscarriages. I had scans at 6 weeks with the IVF clinic, 10 weeks for dating, 18 weeks for morphology, 24 weeks and 32 weeks to follow up on growth and single umbilical artery issues. I also had a quick scan at almost every OB appointment (the first being at 8 weeks) and honestly couldn't count the final number. However, my OB was happy to listen to my opinion of which way up bub was from the movements I could describe - and confirmed that I was correct with a quick scan.

I do find it ironic that I was actually booked in for another scan at 36 weeks as initial concerns about small size turned into concerns about mammoth size... Never got to that one as I went into premature labour mere hours after the scan was booked in for me.
