Insight! Please moms & moms to be!

Today my AF is due she normally shows at 12 am the day of. Just went to the bathroom and I got this and also had some tan/brown discharge on my underwear.

Yesterday I had discomfort all day felt somewhat like af cramps so I was sure she would come. Glow is pretty spot on about my cycles. Are there any current moms that didn’t get a bfp until they missed their af? And got tons of this the day of af?
