SO didn’t know what an OPK was after 4 yrs TTC

We have been ttc for 4 years, done tests, clomid, hcg, not <a href="https://glowing.com/glow-fertility-program">ivf</a> yet but maybe. I have been taking ovulation tests for a good part of our journey to conceive a child. Tonight I showed my SO the two dark lines on the stick like I often do... and he says, “What’s that?” What?! Something I show you almost every month and something that will assist us in having a child together!

Am I out of line for getting upset with him? I told him that it’s frustrating we have been ttc for so long and he doesn’t even remember what two dark lines in a stock means?
