I am 19 years old I usually get my periods for every 25-30 days but now it is very late... stomach pain is getting so much.. I don't have any sexual relation.. please suggest me something I am feeling very stress..

Why are you asking this under Pregnancy? DID you have sex in the past (ever)?
Your answer is important, since your pain could be from many reasons. Skipping a period isn't too relevant at this point, because many women skip them normally.

How late is "very late"?

If you are in pain you need to see a Physician - it could be nothing, but it could be a problem. It is impossible to know without seeing you and probably examining you.

I don't had any...

i dont had any....


"Don't had any" what?

For some reason you don't want to explain this. There is no way anyone can help you without more details. Date of last period, how late are you.

Assume you are saying you are a virgin, never had sex?

But at the end of the day, you go to your doctor for a exam.
