How long does it take to find out you're pregnant?

After having sex and if he cumes how many days or month later do you find out your pregnant

if you didnt use any protection. you can bet your pregnant.
you should know this stuff before going off and having sex.
sperm is also in pre-cum.
so its very easy to get pregnant if you did have sex without protection.
grab a pregnancy test or if it still really early ( less than 3 days after having sex)
get the morning after pill or something.

When your due for your next period do a test a couple of days before and after your due. If it shows up negative you are prob not pregnant if it shows up positive welcome to the parenting club.

I did not find out till I was almost three months pregnant... pregnancy tests did not work in my case, also I was on the pill. If you think you may be go to planned parenthood.
Be careful girlfriend guys will do whatever it takes to get in your pants from the age of 12-I am still waiting to find out when they stop... but you have a friend. Go get tested...and you may even request the moring after pill as a backup...I wish you would wait to have sex as parenting is so hard at any age

how old are you anyways??

just get tested...

if you don't get your period..or 5 days after your missed period
