Could I be pregnant?

Beautiful

Been TTC for two months now. Last month I had sex everyday during my fertile window and days before and after. On the day AF was due I started to spot, the second day I was still spotting and later that night I had a very light flow that continued on the to the third day, and now today which is the fourth day AF has stopped. This is completely abnormal for me because my regular AF is usually five days and is very heavy with lots of clots (TMI sorry) sometimes a little spotting after the 5th day. It’s usually so heavy that I’m changing my pads almost every hour or two..Have anyone ever experience this? Answers please
