Ivf due date or hospital and going over!

Kirsty
Hi ladies just need a bit of advice. I'm 39 weeks and 5 days pregnant and due on Saturday following <a href="https://glowing.com/glow-fertility-program">ivf</a>. I was taken to hospital yesterday as my midwofe said baby hadn't grown in a week turns out everything was fine and baby is estimating 7lb 3. My midwife said she won't sweep me until I'm 40+6 then if that doesn't work she will talk about induction at 41+6. The thing is the <a href="https://glowing.com/glow-fertility-program">ivf</a> clinic gave me the due date of 18th June and my hospital is going for 11th June. I'm a bit concerned them letting me go over as I've heard horrible things about babies going over their due date. I have a 9 year old who came at 39+4 at 7lb1 this one is a girl and I'm scared she'll be to big and I'll need assisted delivery I'm only small myself. Could it be possible my actual due date is 18th and baby could be waiting until then? Sorry if all sounds gobbledygook x
