Fake cramps ?’

Faith

Is it possible to have cramps as if youre going to have your period but nothing happens, can this be a sign of pregnancy? I have had a sore lower back, sore knees, and cramps all day, usually when i cramp i have my period within a few hours... i haven’t had anything this time, and im bloated as all hell. Has anyone had fake cramps during early pregnancy? Ive missed my period, last cycle was December 22nd
