Completely normal! I lost 5lbs in the beginning of my pregnancy then gained it back, today I went for a check up and I've lost 2 lbs since my last appointment. So my total weight gain this whole pregnancy thus far has been 10lbs, as long as the baby is developing and measuring right weight gain isn't a big priority.
Yep it's normal I'm 36 weeks and 6 days and Ive been losing weight here and there during my whole third trimester ill lose like 3-4 pounds but I'll gain it right back and lose it again
