Positive opks 2.5 weeks post D&C

I had a D&C for a missed miscarriage on 6/30. Bled on and off for about 9 days then spotted for another week. I started taking opks a week ago and they have been positive every day. I know I'm not ovulating yet, as I have no other symptoms of it. I'm pretty sure it's just leftover hormones from the list pregnancy, as I am still getting very very faint lines on hpts as well. My question is, did track (or try to track) ovulation the first month after a loss before a period? How long did it take?
