Positive OPK?

Shafawn • RicanHermosa 3 gorgeous kids and currently ttc after ruptured ectopic

I took a test this morning and it was negative, but I took this tonight and I think it's positive right? I've never had a positive opk so this is new to me. I'm suppose to ovulate tommorow and I've been having alot of egg white discharge today and cramping. So if this is positive then I can have sex tonight and tomorrow right?
