Mucus tinged with brown blood on the day period should start

Amanda • Happily married for 13 years ❤️ Mommy to 8 beautiful kids

My period is due today. We are TTC and we’re quite active during my ovulation window. I took a HPT yesterday and today, both were negative. I don’t feel pregnant but I don’t feel like my period is coming either.

TMI

I went to the bathroom and wiped and there was some CM streaked with old (brown) blood. Not a lot, just enough to notice. I don’t have cramps or anything and didn’t notice cramps or spotting from O until now.

Any suggestions?
