LH surge or leftover HCG?

I had a miscarriage at 9w6d that resulted in an emergency D&C; on April 10th. I took both of these this morning just for fun. It’s hard to tell, but my pregnancy test is still showing a vvvvvfl (my guess is leftover HCG). Would that faint line be the reason my ovulation test came back positive? Or am I actually ovulating again?
