Weight fluctuating.

Hello, fellow plus size mamas😊 I'm currently 5w5d pregnant with baby#2 and am noticing that my weight has been fluctuating quite a bit since last week. This morning, I weighed myself at 219, and it tends to go anywhere from 217 to 220 some days (I just don't remember putting on weight this quickly with my first pregnancy). I worked hard this summer by exercising and using the myfitness pal app and lost 25 lbs. I'm trying to be as healthy as I can through this pregnancy and not put on too much weight, as my bmi is already high. I swear my belly looks bigger already, but I'm guessing bloat? Anyway, wishing you all happy and healthy pregnancies!
