When I was in my first trimester I lost 6 pounds but my ob told me it was normal. I recently went in at 13 weeks and weighed 163 and then just got checked up again at 17 weeks. I was 157. I'm also noticing my face is really getting thin aswell. I'm going to my normal family doctor today for a sore throats and stuff nose. If they weigh me and I've lost more weight what should I do? I brought it up with my nurse at the ob but she completely ignored me and didn't even answer me.
