Ppl help needed

Jacqueline • Mummy to twin boys after 2years ttc 💙💙

So according to this app I’m in the run up to ovulation so I started testing yesterday and today, I thought my tests would be starting to get a little stronger but to me they look like they are getting weaker. I test in the late afternoon at 4pm. Today I’ve got super stretchy cm and twinges/cramp in my right ovary so I think ovulation is coming soon but tests are saying different 😩 I’ll pop pictures off opk in comments
