Spotting Day Before AF Due

Kanay
Hey Ladies! I think I'm out of the game this cycle! 😞 I'm NEVER early and AF is due tomorrow. I just started Spotting and I'm pretty sure it's her. I'm not sure if it's implantation bleeding or not because it actually can vary in color. I guess I'll wait to see how long it lasts but I'm trying not to get my hopes up. Anybody thought it was AF and it wasn't or were one of those whom had a "period" for the first month or two?! When should I test again? I'm def cramping like regular btw and breast just a little sore.
