If you skip this month, might try a blood test at the doctors just to rule out possible pregnancy (they don't always show up for quite sometime on urine tests for some women). It would be the first thing your doctor would do anyway, rule out pregnancy. Or, you could wait until May and see what happens when your period would be due then and visit your doctor if need be.
