Weight gain

Ha

Hello ladies! So I am 12 weeks pregnant and I’ve gained over 10lbs.. starting weight was 135lbs and now I’m 150lbs... I thought it was normal to gain a lot of weight in the first months but my doctor looked shocked when she viewed my chart 😞 I don’t over eat.. I eat the same things I’ve always ate, but gaining so much weight.. idk if it’s normal and idk if I should be worried.. I didn’t ask her why she gave me crazy eyes because I was sort of embarrassed. Should I be worried??
