Hi Lilly, so far I've only had any major swelling when I've overdone it during the day and mine's usually gone by morning. I have had to take my engagement ring off a couple of weeks back though as my fingers had started to swell to the point it wasn't comfortable to wear it anymore.
With your fingers stiffening as well I'd definitely be giving the hospital a call and telling them your concerned about it & see if there is anyway they can fit you in for a earlier appointment or see if you can get in to see your GP. Swelling at this stage of pregnancy is perfectly normal but it can be a sign of something more serious as well.
And thanks smile, this is bub no 3 for me, I have a 3yo DS & 2 yo DD already.
