Period ended today

So i started bleeding lightly 3 days ago that got a lil intense but AF came 2 weeks early .i just stopped bleeding this morning and as i was getting ready to take a bath i had discovered that my breasts are sore starting from the armpit area to the sides of my breasts. I thought i had implantation at first but realized it might have been an early MC..WHAT SHOULD I DO?? Could i still be pregnant?? For the last 2 weeks i have been experiencing symptoms but just got the soreness in my breasts..HELP!!
