Sharp pulling pain in belly button?

Julia • Married almost 10 years. 2 kiddos (8 & 2) and our last one on the way. 🤰🏻
It feels like a fish hook and someone is pulling it. It hurts pretty bad. I remember when I was pregnant with my daughter I use to get this pain. But I just finished ovulating. So what else could it be? Anyone experience this. 
Ps. I have regular bowels.
