First day of previous menstrual cycle was May 22, and it lasted till June 2nd. I had unprotected sex last Wednesday, have bled for the last five days; but we find that weird, because my next period isn't due for awhile...

Is there any chance I maybe pregnant?
Was going into the doctor on Friday to have a blood test run, but if I am pregnant will the hormone show up by then?

Thanks in advance!
