Am I Pregnant?? I Have Conceived On My Ovulation Which

Am I pregnant?? I have conceived on my ovulation which is 7-9 of October 2016 I started bleeding on 17-20 it was heavy until the 4th day it got light then it stopped that evening then on the 21st I spotted only once or twice. I had no cramping. My period is on the 23rd of October I've been very emotional about random things that don't usually bother me. I have been pooping more than usual.
