Did she O?

Hello ladies! I love this app and I have recommended it to my best friend. She's been trying to conceive for a couple years now. She is going to possibly start fertility treatments. I know she's on a few medications including metaformin. Drs are trying to see if she is ovulating. She has an appointment to see on September 6th. But she was telling me she can't use OPKs, she said they don't work for her. She happened to try one while I was talking to her. She did get a result. She has taken a few in the last few days. She sent me a picture to ask if she missed her ovulation. I told her I don't think so because the top tests look like evap. I told her blue dye is notorious for that. Ladies what do you think? Did she miss her surge?

This picture was taken yesterday and sent yesterday. If you look at the left side of the test line it's dark then fades!
