What does "i guess i do have same problem with other" mean?
Are you sexually active? If so, you may want to take a pregnancy test. If not and this is the first month you've missed a period I wouldn't stress over it for now.

They can be lots of reasons for a missed period other than pregnancy. Stress is the most common although there can be more serious reasons. See here for more info http://www.womenrepublic.co.uk/health/missed/
