Did I have implantation bleeding or my period

So before my period i experience all the early pregnacy symtoms and I would say I ovulated on day 20 which was 16 of June as I had a very dark line on my test anyway my period didn't start the way it was meant too 3 days later then bled which I thought was my period but i only bled for 2 days normally my period is 5 or 6 days long and today no blood at all and my nips have darken and my sense of smell and taste is really off done pregnancy test but is negative but the ovulation test is positive I mean can you have a positive ovulation test after 2 to 3 days of bleeding
