Tw Miscarriage bleeding

I don't really know what category to even put this is so I do apologise if its in the wrong one.

I started spotting last Monday (14th) started bleeding with a flo and clots last Friday.. confirmed it was a complete miscarriage when I had my scan mid week.

I am still bleeding with clots, 7 days since the spotting turned to bleeding. How long does this usually last?

How long after the bleeding stops am I likely to ovulate. This app says I ovulate in 4 days but I'm still bleeding?..
