Walmart frustration

It was late at night, my husband and I stopped at Walmart on our way home to pick up a few things. With AF leaving and us being out another cycle we needed some pregnancy tests for this cycle, so I bought enough to fuel my tww anxiety . 7 of the Walmart cheapies, like 5 of the first response and one digital. The girl is ringing me up and she remarked that she didn’t realize those test were only 89cents and I said something like “yeah it’s easier when you are buying a lot every month, it saves money”

She then proceeded to go on and on about how she just found out she was pregnant and that she wasn’t trying and her boyfriend was a pos, and I kept a smile on my face the whole time but I damn sure bawled my eyes out when I got to the car. I felt like a crappy person for being upset with a stranger that she was pregnant and I wasn’t. That she wasn’t even trying and she seemed mad that she was, and my husband and I are doing everything right and it hasn’t happened. I hate that I’ve become this jealous person 😔
