Discharge ?

Cycle day 19, haven’t been testing and tracking besides paying attention to mucus. Bit of a back story, I had a miscarriage Sept 4 at 5 weeks pregnant. Didn’t bleed again until 6 weeks after but only for 3 days. (Oct 17-19) and then again 17 days later, so Nov 1-3. That first cycle was only 17 days long. I am now on cycle day 19 and don’t know when you expect ovulation or period. I haven’t had any EWCM but normally do between cycles. Any one can relate to this? When did you ovulate? Do you ovulate without the discharge? And when did you get your second period of first one was short or when do you think I should expect it ? Before miscarriage cycles were usually regular 28 days.
