What is going on with me?! 😅

I am so confused as to what is going on with my body. I don’t have my period until the 12th, however today I’ve been off and on “spotting or bleeding” off and on like this since this afternoon along with cramping. Any insight on this? 😅 Also Saturday was the day after my most fertile day according to Glow and only once out of that entire day I wiped and there was very very faint blood. What the heck is going on or could be going on? No I am not on birth control.
