I was the same in early pregnancy i lost about 7lbs but very very slowly i started to gain weight, even now at 32wks ive only gained 14lbs in total ,sum weeks id gain 1lb and others id lose 2lbs so dont panic aslong as baby measures fine at ur scans it will b fine :-)
I lost 45 pounds with my first pregnancy. And with this one i lost 25. My doctor just kept an eye on the babies to make sure they were growing ok. It is totally normal to lose weight in early and sometimes late stages of pregnancy. Good luck.
I'm having the same issue I made another appointment with the hospital to get checked tomorrow
No it's not normal. You need to go see your doctor.
