Normal when you're still having morning sickness. But when you reach your 3rd trimester, you need to gain some weight. This is when you baby is picking up weight fast at that stage
I experienced the same thing during my first pregnancy. It's normal thou... every pregnancies is different and thank god 🙏 I don't experience this with my second pregnancy.
It's normal but best to consult your gynaecologist, take care!
U may want to highlight this to your doctor on your next visit
