My last period was march 31 and ended April 4.. Could I have my period again in April, or could I be pregnant if I havt got it and I haven't got it yet and its May 2

While it may not be the norm for you to be even a day late, it usually is not a concern to have an off cycle. It happens now and then. Do you know the usual length of your cycle?

Give it another week, and if still no period, try a pregnancy... making sure you follow the directions exactly.

Doubtful. Get a test.
