17 weeks 3 days and only gained

Junebaby2

1 pound my doctor said I should have gained 5-10 pounds. I have super bad ms and zofran works when it wants. At 6 weeks I was gaining a pound a week but loss all of it. Baby looks good and as of yesterday was measuring 3days bigger. I guess what makes me nervous is I was bigger with my son. I guess they are right when they say every pregnancy is different and I'll just have to take it one day at a time. tia
