Positive? Update:

I had my mirena removed 5 days ago and started light bleeding yesterday. The top opk is from yesterday evening and the bottom two are from this morning. Is this ovulation or is it possible the mirena removal is tricking me?

Update: the test below was taken Saturday. Does this mean that I peaked yesterday? I never get bold positives on the opks.??

The picture below is from today: looks like I'm almost positive for ovulating..? But yesterday's test seemed lighter? So confused!! Any thoughts??
