OPK craziness ...

Tori • Angel Momma. Bentlee&Braxton 10.12.16 Growing our rainbow ❤️
This is our 4 cycle TTC after a loss in October, I decided I would do OPKs this month since I wasn't having much luck with just charting. 
I had a deffinate positive OPK on 4/7, and of course lots of baby dancing. Fast forward to 7DPO, I took another ovulation test, and get another strong positive. 
Anybody have any advice on this?
