Help me cause I'm getting nervous

Niyana Denyce
I obviously had unprotected sex on the highest % risk days (2) 😞 on top of me not getting my period yet I don't know what to dooooo or think! I've taken 4 test and all negatives but still 4-5 days late. Could I be pregnant has anyone else gone thru this ?????  I feel cramps but no bleedingÂ
