Haven’t gained anything in a couple weeks - 28 weeks

Hi! I haven’t gained any weight the last few weeks. Would you be concerned?

Couple notes -

-last appointment in early January I was measuring fine

-I’ve gained about 15 lbs the whole pregnancy, my starting weight was 125 and had a normal BMI at 5’6”

-only change I’ve made is eating a few salads a week whereas before I just was eating carbs or whatever.. but I still feel like I’m eating a ton..

-with my first pregnancy I steadily gained at least a pound a week at this point!

Thanks!
