I'm concerned that I'm not gaining enough weight. I was 122 lbs before I got pregnant, I gained 6 lbs during the first trimester, and now I'm 16 weeks and still stuck at 128 lbs. I haven't gained anything in a few weeks even though I've been vomiting far less (almost not at all now). I called my doctor and they said to "keep and eye on it" and "monitor it" which I'm doing. It makes me a little nervous. When I bring it up, everyone sarcastically says things like, oh just wait, you'll gain a ton. I don't want to gain it all at the end in an unhealthy way.
