Weight gain, or none?

Raymond
I am a first-time mom-to-be I just hit 16 weeks and 2 days and for the first 3 months I actually lost some weight because I couldn't eat anything and now I'm just leveled out and haven't gained any. I've noticed and my husband have noticed that my hips, belly and butt have gotten wider but I still haven't gained any weight is that normal? I'm not to worried but did anyone else have this experience then maybe just pop. Right now I just feel slightly fatter, not pregnant. I was always bigger too.
