feeling down

This may seem stupid to some, but I just left my doctors apt. and found out that I've gained about 25lbs so far. Before pregnancy I was 125, and now I'm 148. I just feel so upset with myself. This is my third pregnancy and with my other two I gained a healthy weight. I'm only 25 weeks and so scared of how much I'll end up gaining😔 I do my best to workout still and eat healthy but right now I'm just feeling kinda gross. Not a good feeling
