no movement???

Noemi • Proud FTM to my beautiful baby girl Melanie Jazmin
I'm almost 23 weeks and feel my girl kick and move around everyday, there's only been a couple times where I didn't feel her for a whole day but today marks day 2 of feeling no movement, or I feel something but I'm not sure it's her maybe it's gas or something and I'm getting light cramping.. could this be a bad sign?? It's my first pregnancy and I'm really excited so anything makes me worry. What do you think?
