Q:Cramps but no period

So i have unprotected sex with my fiancé all the time and for about a month now he's came inside me this use to happen before and I always had my normal period on the correct date.. Well now this month I'm a week late and I'm cramping like I'm going to start my period but nothing comes the cramps come and go just like a period but for about 4 days now ... I get my normal period symptoms back hurts, emotional, and cravings but the only new thing is my boobs hurt every day as if my period was coming but no... Should I take a test sorry for the long paragraph
