Third trimester, slow weight gain

[Lexyness]

Sorry I know lots has been posted about weight gain but the search thread is useless for me!
I’m 37 weeks tomorrow and stupidly weighed myself again this morning! I then proceeded to use the weight gain calculator and I haven’t gained enough weight apparently!
Thing is I lost Weight with dc3 (5lb13) and my maximum weight gain with dc1&2 (5lb12 & 6lb6) was only 8lb each time. This time I feel like I’m carrying a baby hippo as I’ve gained 13lb! I literally feel huge!

I’m not concerned as I have had regular growth scans and according to them baby is growing well - in fact has gone over her initial centile line - but tbh I don’t think I can take any notice of their estimates 🤣
More just wondering what other people’s experiences are I suppose? Also I don’t seem to have put any weight on at all since before my last scan, but my bump has definitely grown - will see what they say at next weeks scan!

I'm 38wk with number 4 and have put on 11lb in total. He was predicted to be nearly 9lb at 37wks and I've consistently measured 2.5wks ahead on fundal height.

Put on a stone with dd2 and 3 they were 8lb15 and 9lb10.

Put on 4.5stone with dd1 and she was 8lb11.

Thanks @EverythingNow so it literally does sound like there’s nothing in it at all then - doesn’t make any odds to how much weight goes on lol!
My colleague just told me she weighed herself at the start of labour and then after as well and the baby alone weighs over 9lb but the scales said she’d only lost 5lb - she was gutted! Hope that’s not the same for me lol!
I don’t get my fundal height measured due to the growth scans so have no comparison for that but I’d be interested to know lol! Bit late to ask now though as Next week is my last appointment with mw lol!
Can’t wait to get my baby hippo out now though 🤣🦛
