I’m concerned about my lack of weight gain!

I’m 28 weeks pregnant and many people keep telling me I don’t even look pregnant. They say it looks like I’ve just gained 10 lbs.

I have a small frame... only 5’2. My pre pregnancy weight was 125 and I am 139 now. That’s 14 lbs. Is that enough??

My appetite hasn’t increased at all during pregnancy other than needing to eat more often. I’m not craving any fatty foods so maybe that’s the problem.

Do you have any suggestions, thoughts or advice? I really want my little boy to be healthy and I want the weight to come one.
