Normal to lose weight ?

I’m currently 24 weeks pregnant. I started off at 108lbs and this is my second pregnancy. I was 112lbs when I went to my apt 2 days ago and I weighed my self today and lost almost 2lbs. I’m a little worried. Is this normal? I never lost with my first pregnancy. If anything I gained 25 lbs by this point in my first pregnancy. I am much more active and eating healthy but I don’t know if it’s actually ok to be losing weight. I’m not trying to lose weight. I’ve been eating as normal so I don’t know what’s going on.
