Missed period ...!!!!!!

Mary
I'm 2 days late and don't feel like my period is coming. I usually have cramps the week I'm getting it and about 2 days or 1 day before I get bad cramps and know it's coming but this month I don't feel that I only have mild cramps that come and go and I have some symptoms of pregnancy. I'm very tired and recently very very forgetful idk if that's a symptom ? I have headaches and constipation and o have whitish yellowish creamy cm and usually before my period I dry up. I did have unprotected sex so can I be pregnant or should I wait it out ?
