Lil legs 😐

I’m 22 weeks pregnant 2nd pregnancy. Before I got pregnant I was a regular thick girl. Thighs and butt matched no waist. But lately I noticed my legs look small and my booty has shrunk. I’m worried my body won’t look the same ever again. Why are my legs shrinking when most of all pregnant women complain about big thighs. I don’t really eat as much with this pregnancy because morning sickness is still a factor. I wonder if me not eating as much has something to do with it.
