AF this early?

So AF has been visiting the days scheduled. Im not supposed to start until February 7th and i already ovulated last week but lately I've been feeling like AF cramps but they're very light and not painful at all. I baby danced 3 days of me being fertile. A lot of people always tell me that they dream of pregnancy or getting a bfp right before they test and they end up being pregnant and ive never had pregnancy dreams until last night. Obviously it's too early to be getting symptoms and to get my bfp but what do you think? Could it just be AF coming a week and a half early or could I be feeling implantation cramping?
