Leg cramping

K

Usually before every period I get a really bad leg cramp. Last cycle AF came on time but no leg cramping and only bled for a day and a half. Since then I have had constant twinges in my abdomen and today (CD 11) my leg is cramping like AF is about to start. My cycles are usually 26-29 days. I took a pregnancy test on Monday and it was negative. Could I still be pregnant?
