What does this mean?

I got off my pill late November. Obviously when i stopped taking them, i got my period. I havent had another since, though i always did have irregular periods. For the last few weeks, Ive been cramping throughout the day (and i never had cramps before or during a period unless i missed my pill). I've had this light red-pinkish discharge maybe 2 weeks ago and yesterday. I've always been a sleepy girl, could sleep from 4-7 and go right back to bed at 10 for 6 hours. Is there a possibility im pregnant? Help.
