Starting 2nd Trimester still losing weight! HELP!!!

Rachel
So I have been sick since week 6 almost right after finding out I was pregnant. I was on zofran that didn't work and now diclegis (helps a bit but still vomiting every few days). I had a check up with my OB today and I lost another 3lbs since my last visit 4weeks ago. I was tiny to begin with at a starting weight of 112lbs (now 105lbs). Baby is doing fine which I am so thankful for! My OB said in 2weeks when she wants to see me again if I haven't started to gain any weight then she is going to have me do home health care. I am not sure what that means exactly but it scared me and I am now freaking out! I don't know what else I can do. Anyone have the same issue? Anyone know what my OB meant by home health care? Sorry for the long post just frustrated with myself and my body at this point and I keep hearing the same thing from everyone telling me to just eat more and it isn't like I'm not eating, I just stop if I'm full or start to feel sick because I don't want to vomit anymore. I just don't know what to do and just feel like crying now lol... On a lighter note the pic is how we announced my husband and I were expecting :)
