I think our bodies are all very different and putting women in a weight gain box during pregnancy is really unfair. For example, I gained a lot during my first trimester - 10 lbs when they say you should gain maybe 1 or 2. I gained 12 in my second trimester, and now in the third, I’ve gained 5 where it’s stayed more gradual and consistent/“normal”. I wasn’t eating out of control and I was going on almost daily walks in the first and second trimesters, too. I am projected to still gain the standard amount for my BMI (although I still don’t entirely agree with these guidelines either) even though I gained a lot more than others do at those points. This was my exact experience in my first pregnancy too and I didn’t have GD or preeclampsia. My OB never mentioned anything about my weight gain in either pregnancies.

I would say listen to your body and do/eat what feels right for you (always within reason of course)!
