Irregular and ttc

My period is 7 days late I’m afraid to test because I don’t want it to be a negative again I didn’t use opks this month but I just went by the app because I was on vacation ... anyways I’ve been cramping and I have sore swollen boobs typically my boobs only hurt 2 days before my period starts and I never cramp unless my period is actually here but for the last week now I’ve been cramping
