So I thought I ovulated on 1/21, but wasn't sure because my cervix didn't feel open. I kept testing and definitely got several positive opk on 1/27. I was worried that it might not be it still so I kept testing everyday. My opk never went lighter like they usually do and hcg is

negative. My opk did this when I was pregnant with a chemical last May.

Do you have any idea what it is happening now? Has this happened to anyone on a cycle they got a bfp? Did I definitely ovulate? The pic is my tests from 1/27 on. The right one is now.
