Curious 🤔

So, this has gotta be an indent, right? Have an irregular cycle, so wasn’t sure... Took positive OPKs on CD 13, but didn’t test before then... Was gonna have a few drinks this evening with my husband, so took a test just on the off chance... It’s a real squinter, but according to my calendar, it’s gotta be an indent, right? Posted a photo of the test and of my calendar. Maybe I’m just blind... 💁‍♀️🤷‍♀️
