Testing to much?

mac

So I am almost 6 months pp. been <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> with opk to try and not get pregnant. Yes I could take my temp I know but I don’t ever wake the same time and it’s just not possible.

Well my husband is mad I am buying ovulation tests every month. He’s mad and says I’m buying them to much. Is he wrong?
