Period two days late with no cramps, should i be worried?

My period is two days late and still no sign of it at all, im not even cramping or anything... What could that mean? I have a 29 day cycle and im usually right on every month, but its day 31 and I cant find anything on the net about whats going on, just...

stuff about missing periods and having cramps, but im missing both. Help..? When do I start to worry here??

Do you have reason to worry?

Have you been having unprotected sex?

Cycles can go awry at any given time. It isn't written in stone that you must bleed every 29 days.
Give it a few more days, then see the doctor

I havent had unprotected sex lately... not since like mid-august anyway. after that my guy and I had a long talk and decided that since neither of us is ready for kids (im 17 in college and he's 19 joining the marines) that we need to always use condoms, and when one breaks I take the morning after pill... so lately we HAVE been usin condoms, im just a little concerned with my period bein late an all and still NO CRAMPS... I always get really bad cramps a few days before so its a bit strange... and aside from back when I started usin birth control about a year ago (but I stopped in january), my period hasnt been irregular since I was like 13 or 14.

but I suppose I'll give it a week?

good to know, VERY good to know lol
but how long do you think I should wait before I DO worry? like a week, a week and a half??

I was a week late when I took my first test and it was negative but then I took 3 more and they were positive. I had my son 9 months later. I would wait atleast a week and then take a test. I only didnt take my pills for 2 days and thats apparently all it took to get prego. for me anyways. good luck
