should I test?

I've missed a few BC pills, & had unprotected sex. My period should have come yesterday, nothing. I'm having cramps lower and lighter than usual. Hella headaches, peeping more, CAN NOT GET ENOUGH SLEEP! My coworker had a dream abot me the other night that I was pregnant, she's dreamt about other people being pregnant they were. Do you think I should test? 
Update!! Today I woke up puking. I puked a few days ago as well. It was the day my coworker had the dream.
