17+2 and still no weight gain


I was slightly overweight to begin with so I know I'm not recommended to gain as much but starting to worry if baby is getting enough nutrients to grow properly. At 17 weeks still haven't gain anything , originally lost about 5-8lbs due to being sick, now just resting at my starting weight. Still dont have much appetite and find myself forcing small meals in. Going to ask my doc at my next appt but any one else experience this ?
