Am i pregnant

Hi, i got last period on May 3rd. My menstrual cycle is 26 or 27 days. so, my ovulation day is on 10th or 11th day from May 3rd. I felt that i am pregnant after 10 to 11 days of my ovulation period due to tender breat and symptoms like dizeeness. my normal period date is on 29th May. I didnt get period on that. but on 30th May night, i started getting light period which is continued next day also. It looks like normal period but not too much of bleeding. am i pregnant?, or its a regular period and something happened to me.
