Positive ovulation test 11 days after misoprostol?? Please help

Had a mmc at 8 weeks, took misoprostol 11 days ago. Went to the doctor last Thursday (5 days ago)to confirm with ultrasound that everything came out. It did. She said to start testing for ovulation again day 10 even if I’m still bleeding which I am. I tested this morning and got this..I don’t usually ovulate until day 16-18 not sure what this means...what do you guys think??
