DH High Fertility! Something funny/frustrating!

Meg
So- been using clear blue opk this month. I've had a week now of high fertility flashy faces. Was thinking something is up as hadn't reached peak yet- so I tested my DH- to see if working- HE GOT HIGH FERTILITY SIGN TOO!!! 
​What do I do now?! Haha I'm thinking I've got a faulty batch?!
