Positive OPK?

Hi,

I recently had an EP which resulted in me having to get a mtx injection. I bled for about 14 days after that which brings me to this week, a full two weeks after I stopped bleeding.

I am trying to figure out what my new cycle is by testing for ovulation and calculating from there. I have never used OPK before so I'm not sure what I'm looking at. I know that if the test line is as dark or darker than the control line, it's positive. As you can see I have 3 (what I believe) are very positive OPK's.

These OPK strips are from the following dates:

9/5 PM

9/6 AM

9/7 AM

9/7 PM

9/8 AM

I'll be taking another one tonight and until theyvstsrt to lighten up.
