Is it ovulation? Lost

Edith • 2 kids ttc#3 😊
I have no idea what's going on with my body but lately I have been cramping and in pain down there. I reventlyhad a miscarriage. Don't understand if it's because I am ovulating again or what but I have sore breast and nausea and AF isn't due until the 15is of august. Ladies any idea? Help!
