Is this normal for my first month off the pill?

I have been on the pill for 7ish years straight. This is my first month off the pill and first month ttc. The app says I'm ovulating right now and so does my opk. But I'm just wondering is it normal to have extreme cramping (like really bad), sore bbs, extreme fatigue,nausea, and I even threw up twice today? I would appreciate any insight....it has been a while since I've been through this. Thank you!
