Hunger Pains while Breastfeeding

So I'm feeling concerned and just want to know if other moms have experienced this.

My daughter is 7 months old and is nursing a lot at night recently (teething). The last few days I've been eating and right after I'm getting hunger pains. At least, it feels like hunger pains. It's crazy. No matter how much I eat, it always feels like it's not enough. I never had hunger pain feelings like this with my other kids. Anyone else have this? The pain is just like hunger pains so idk what else it could be?
