Hi.i am 25 and didn't had periods since last 2 months. i had the same problem last year in same days for 3 months. after that my periods were normal.?

Depends: Sometimes bleeding is not associated with ovulation. If you are on the pill, it's not unusual to miss a period, check a upt as well. Hard to make anything of the timing but missing periods can be a long conversation. Good luck.

See detailed answer: Although this is likely related to stress or other normal menstrual variation, you should be tested for pregnancy if sexually active, and other conditions such as thyroid disease by your doctor.
