Measuring 34 at 38+2

[Matilda30]

Hi,

I had a mw appt this morning at 38+2 but I'm measuring 34 which is what I was measuring at my last appt at 36+2 (although different mw) so I was sent for monitoring-I've just got home from that-his heart rate was fine n I'm being sent for a scan in the morning as they couldn't fit me in today. I have an added worry in that I'm having an ELCS (for mental health reasons) on Monday at 39+1. However I wasn't sure of my lmp date so now I'm worried that he's not growing and also worried that I won't actually be 39+1 and he'll be born too early and be tiny. However when I've mentioned this, I've been reassured over the accuracy of dating scans.
I think I'm just after reassurance from anyone who's had similar experiences/concerns over their fundal size and dates .

Dating scans are fairly accurate to be honest. Have you had a growth scan? Bunko measuring is very inaccurate.

I had a growth scan at 28 weeks and he was in the normal range. I just wasn't sure whether dating scans were completely accurate or if they went off your date a bit. My very much estimated due date was 21/9 and they moved it to 20/9.
