Help me understand.

Keera

Hey everyone. I took provera for 10 days and 4 days later my cycle started. Now I am on day 10 of my period and I'm cramping so bad like my uterus can fall out. Also I have pressure like I have to poo, but I don't have to. Hellppp. Has anyone had this happen? Will I ovulate with this long period? I also take myo-inositol powder. Am I supposed to take it during my cycle?
