Am I pregnant?

September 24th I had unprotected sex my ovulation period was between September 23rd -28th. On September 30th I've noticed I felt really wet all the time when i went to wipe nothing was there and it was odorless I had that for a few days , around October 2nd I started feeling cramps and pressure on my lower belly. I felt that for like two days. Yesterday October 4th I went to the bathroom and wiped and the tp had a light pink blood , today this morning I still see light blood, but around noon today I went to the bathroom and when I wiped it was a bright red and had increased and still is that way. I know to many that it may sound like I got my period but it's not due till next week on October 12th. Also my period the blood is a lot heavier and with clots usually. I'm not sure if this is implantation bleeding or if I miscarried or if I was pregnant at all. I just don't know if this is something I should be concerned about.
