5 days late

I had unprotected sex with my close friend. He knew I was on my period and we had sex anyway. My period started March 3rd and we had sex on march 5th. My period shouldve happened on friday... Its sunday now, April 3rd. I have no symptoms of cramps from PMS or spotting. Im bloated and have a sense of smell..Im really debating on getting a pregnacy test soon or its all in my head. Any advice?
