Period after MC

Jasmin

I found out I was pregnant on the 30 of December blood levels went down on the 1st of January I was suppose to start period on the 2 obviously I didn’t but I MC and started bleeding on the 7 finished on the 11th. Took OV test on the 13 it was positive? Pregnancy test was negative by the 20 of January? When should I expect my next period? Was the ovulation test valid?
