Peace, have another hug. I anticipated being bollocked by the mw at my booking in due to being a fatty, so I mentioned it first. Like you, I really struggle to lose weight, but I eat pretty healthily, cycle 18 miles a day (pre-pregnancy), swim a few km a week, and do a lot of walking. My bp, pulse and menstrual cycle were all fine as well.
I've put on 10lbs since my bfp (currently 13+1) pushing my bmi up to 44 (I'm really short as well which skews the stupid bmi thing apparently, not that the mw would take that into account).
She seemed quite taken aback when I asked her if being both old and fat heightened the chance of pre-eclampsia, and I was like, 'well I am, it's fine, you don't have to skirt around it and I don't have to apologise for it'.
I'm well aware that it's not ideal to go into pregnancy at this weight, but there's fuck all I can do about it now except try and eat healthily for the next six months and stay as active as possible. They asked me if I wanted to go to fat pregnant lady clinic as well, I refused.
So yeah, basically what ffallada said
