Pregnant??

AF was supposed to start on the 5th.....I had a tiny bit of brown discharge on the 3rd and 4th only when I wipe. Then on the the 8th I had bright red bleeding pretty heavy....then after it is back to brown and very very light only when I wipe again!!! My periods are always 6 days straight with bright red bleeding for 5 days then brown the last day!!!

Could I be pregnant? I'm just confused because this is not normal for me!!
