help me please

Abigail
I haven't gotten my period whole month of February And this has never happened to me, my period always on time, And yes "me and my boyfriend" never used a condom most of my friends point out to me my stomach getting swollen and yes it's kinda swollen also 2 of my friends had dreams of me being pregnant my symptoms are swollen Breast I'm always tired I once in a while get nauseous and I'm more hungry then ever and I feel a knot in my stomach . ( Should I wait and see if I get my Period next week or should I do a Home test?
