To worry or not to worry?

Should I be worried that I just started my period after I already had it and it ended about a week ago? I'm due for a pap smear soon, so I think I'm going to try to go early if possible, but until then, is something to worry about? Hate these cramps. I didn't bring anything with me because I already had it, so I didn't think I'd need anything. Why is mother nature so mean sometimes? Maybe I need to give her a snickers.
