What day is cycle day 1 after a miscarriage?

Pasha • Rainbow baby June 15, 2016 ❤️
I started miscarrying March 13. I officially passed the sac, heavy clots and heavy bleeding March 14. Is March 14 considered as day 1? I did not have a d&c. I know its almost impossible to tell but around when would I ovulate? Can anyone help me with this please?
Thank you
