difference between emplantation bleeding and period?


I just had AF Sept 23-27, two days ago I had very light spotting. Yesterday had nothing and then today I have had heavy spotting. I am normally on schedule with my periods maybe a day early or late, but nothing out of the norm. I haven't had any cramping, pain, or discomfort. Should I go to the dr or could this be emplantation? How heavy is emplantation bleeding or I'm I just having a crazy period? anyone ever experience something like this? sorry if this sounded like rambling, just want a BFP soooooo bad!
