Pregnant or not?!?

Okay ladies I’m a bit confused! I had some spotting Sunday evening. It wasn’t the normal color for spotting it was pink and brown. Thought maybe it was implantation bleeding since my period wasn’t supposed to start till this Saturday. Well I woke up Monday morning and I was bleeding. Not a whole lot. Chalked it up to my period just being early. Well it last one full day. I bled semi heavy. And Tuesday it was light and today I spotted a bit that was it! My couches are usually 7 days. Think I could still be pregnant?? Or what the heck is going on?
