Im 5 days late for my period.My breast are tender,Ive had some light cramping but no period. Ive taken three home pregnany test an they all have came back negative. What should I do? Could I be pregnant?

You could just be having an off month and be late still. Or it might still be too soon for a positive test. I'd wait another week and if you still have no period and negative tests check in with your doctor.
