Is implantion a possibility?

Ashley
Having pains im my left lower abdomen what kind of feels like little cramps. What is this? Ive had sex 2 days ago...is implantion a possibility? Should i be worried...or is it too soon? My ovulation time was two weeks ago around the 22nd. But my period is in a couple day...could this be signs of  my period symptoms?
