Not gaining Wright

knottiebef3f65d1c1a50d6

So I'm a little over 16 weeks and I know in the second trimesterbits recommended to gain 0.5 to 1 lb per week for the second and third trimester. I lost a few pounds in the first trimester due to being sick all the time but they prescribed me some nausea medicine and I went back to my normal weight but have yet to gain more and when I weighed myself this morning I lost what I had gained back. I'm naturally thin but usually gain weight pretty easily. This is my first pregnancy should I be worried?

You are only 16 weeks, cherish not having extra weight right now, as you progress you will gain some.  Not everyone gains a ton of weight.  If you are concerned, call the nurses line at your doctor office.
