Could I be pregnant?

I had my period oct 22 and according to the app I use I was to ovulate on November 4 but a ovulation test said it was a peak day I had unprotected sex on nov 11 I had very watery bleeding that was bright pink at first and then was red and no clots my period is 5 days late and pregnancy tests are coming out negative could I possibly be pregnant

I would wait about a week then take another test… if you are, your hcg levels continue to rise daily so it will show a positive by that time
