Omg these OPKs are making me crazy

Dayjia

I be been testing twice a day since 6/10 and my lines are always very faint. So I thought maybe I had a cheap OPK. Ordered pregmate (they haven’t come yet) but this morning I took the same test I’ve taken all along and I got the darkest negative I’ve ever gotten and my CM seemed to change to creamy. I got soooooo excited, I just knew I’d get a positive test on my even test or tomorrow. Then on my evening test it was light again😩😩😩 I’m so confused!!
