MY LAST AF WAS FEBRUARY 19, ACCORDING TO THE CALCULATIONS I WAS OVULATINIG MARCH 5TH, I DID HAVE UNPROTECTED SEX THAT MORNING. NO BEING MARCH 10 I HAVE HAD AF CRAMPS FOR FOUR DAYS AND A LITTLE TIRED AND IRRETABLE. I NEED TO HERE WHAT SOMEBODY ELSE THINKS.

There is a possibility that you might be pregnant, from the cramping that you've had. Just to be sure, get a pregnancy test kit from your nearest pharmacy. Good Luck!
