Any mamas still losing weight?

I’m 17 weeks tomorrow and at my midwife appointment a few days ago I noticed I am still losing weight. Down about 8 pounds since I became pregnant. Midwife isn’t concerned and asked that I gain at least 1 lb. by my 20 weeks appointment. This VERY different from my first pregnancy and I’m a little concerned.

Has anyone else continued to lose weight this late in pregnancy? If so, when did you start to gain?
