Can I be pregnant?

Hi ladies. So I’m officially 8 days late, on and off cramps the last few days, and white discharge coming out making me think it’s my period until I go and check. My last period was January 16-21, and December 16-21 before that. Had unprotected sex and he did finish inside several days (feb 13,14,15,18,21 and 23rd of feb) however all a week after ovulation according to my app. Can I be pregnant? I am confused! I’m never this late for my period the most is usually 3 days.
