Implantation bleeding or PERIOD?

Leydi
My period was due on 9/22 and at first started spotting pinkish color all the way to the morning. Then in the afternoon I got a light flow with bright red color.on the 2nd day I had still a light flow,and I saw some blood clots.and now today when I woke up, my pad was just clean,but when I wipe I see pinkish color again. Im.confused bc its supposed to end tomorrow. And I usually have symptoms to when Im getting my period,but this time I had no symptoms at all or pain.I just got constipated out of the blue thats it. If anyone can read my post and give an answer to what is going on to me. I appreciate it. Thanks
