Hi @Shortbread74 and congrats! I found out I was expecting the night before my 40th, and baby is now 4 weeks old, having been delivered by ECS at 38 weeks. This was my only option, having placenta preavia, GD, (and a baby sitting upright!). Whilst some women openly prefer CS to vaginal delivery, I have to say my recovery is slow and not free of complications. Unless medically necessary, I would personally prefer to try for a non surgical birth - if you're low risk the recovery can be faster, and being physically wrecked is super hard with a newborn to care for, especially if it's your first and you don't know what you're doing (That's Me!)
That said there are positives- no exhausting labour, no possibility of tearing, etc, but it can bruise you inside just like a regular delivery, and i've has a repeated (and painful) UTI since so it's by no means an easy option.
Hope this doesn't sound negative, just wanted to share my recent learnings.
Oh and re: extra scans- yes I had 2 extra early on with the Harmony (11 & 13 weeks), and booked an 18 week reassurance scan privately as my 20 week date was on New Year's Day and my NHS 20 week scan was going to be held late at 21.5 weeks. I knew I couldn't relax over Christmas without knowing things were ok so dropped for one before.
Other than that my (high risk) schedule of scans was 20 (late), 28, 32 & 35 on the NHS. I ended up having another at 37 when he threatens to arrive before the CS date!
Wishing you fantastic luck for the rest of your pregnancy!
