TMI pic included sorry ladies....but i could use some advice

I was wondering if anyone was in in the sane boat as me. Glow predicted my AF would start on 12/8. But in that day u got nothing. Now I gave this weird sporting which started 12/09. I have had little to no cramping and the spotting is off and on. Ive had no red blood or clots either. Glow also predicted my cycle was to start a 12/4 but instead I had a few hours of light pink to brown spotting. Does anybody know what this is or could be? **by the way I had a long day at work and forgot my purse so please don't judge me lol but I had this pad on since 8am and its now pm
