Am I pregnant? I need help.

My boyfriend and I had sex in the end of December/ beginning of January, we didn’t use protection and I’m not on birth control or anything. Now I’m a little worried because I haven’t gotten my period and it’s overdue. I also have been getting weird cravings, back pains, bad migraines, and my boobs have been super tender. What should I do? Am I pregnant? Should I get a test?
