Doubt I am pregnant but need to know your thoughts.

My period started on October 6th ended on the 10th. I had unprotected sex with my boyfriend on the 15th (cycle day 10) I have irregular cycles. I took my way emergency contraceptive on the 16th about at the 24 hour mark. Didn’t have any symptoms until Monday the 23rd I’ve been bleeding since then and it smells kinda fishy... and is more than my regular period. I also feel tighter than usual in my lower abdomen and it feels bloated I’m also peeing a lot more than usual. How long after my way should I keep bleeding?? Is all this normal? I’m like 100% sure I can’t be pregnant.. I’m not suppose to get my period until the 3rd, is this my period or from the pill.. help!!
