Any ideas?

JM • 28 started TTC #baby 1 June 2016. 2 and half years 🌟

opk is the bottom test taken cd24 at 12am. I had a very strong positive on cd18. So why is my opk so dark at cd24? When I’ve already had my all surge ? The blue is a hpt I took I know it’s super super early to test but I’m a pee on a stick addict.
