Get a pregnancy test now, dont put it off.
If you are pregnant, [and it sounds like you are since you've misses a period for 2 MONTHS now,] there are vitamins that you need to be taking, and you have to see a doctor to find out when your due and other prenatal things have to be done too.
No one can tell you for sure that you are pregnant, because no one is psychic.
Get a pregnancy test, ask a friend to lend you the money and you'll pay them back, tell your parents, how old are you?
You've had 2 months to get a test, when your period was supposed to come [obviously it didn't] why would you have not gotten one right then? Did you have unprotected sex? You can be pregnanct from doing so.
Get a test now, go to a clinic they can give you one for FREE and see a doctor as well. Pregnancy is not a joke.
