I went in for my first visit at 11weeks.. I weighed 198.. doctor asked me how much I weighed before pregnancy.. I said idk maybe 185 .. well I doubt I gained 13 pounds in 11weeks, since I couldn't keep anything down. I am 19 weeks now and weigh 201.. not will the doctor say I gained 16 pounds since I think that's how much I weighed before but it was prolly wrong.. or will they say I only gained 3 pounds.. since really it's all I gained.. ughhh. I don't know
