Lost 15 pounds???

Angel • Aliyah Rose 🌹 1/31/18 💖👶🏾👨‍👩‍👧

I'm only 4 wks + 3 and pre pregnancy I always weighed about 110 lbs since I was in like 7th grade...this morning I weighed myself out of curiosity and it said only 96 lbs! I mean, I've heard that you GAIN weight during pregnancy, not lose it. 🤔This is my first baby so I'm nervous about pretty much everything. I haven't had any morning sickness or anything. Is it normal to lose 15 pounds in the first trimester (or at all)??? Thanks in advance.💕
