Help?

My period usually last 4 days but for some reason it lasted 7 days

From oct 29th - oct 4th

I thought it was over so we had sex on the 2nd. About an hour later I started bleeding again and it lasted two more days. We haven’t had sex since but yesterday I started having some cramping and odorless milky white discharge.. it’s carried over to today and it’s not stringy like my usual ovulation discharge so I’m not sure if it’s ovulation or could possibly be early pregnancy?

Any thoughts? My app is usually accurate with ovulation but since my period lasted longer I’m not sure
