Wow looks like we have some very uneducated people giving answers here. First of all to set the record straight you can get pregnant while on your period. It doesn't happen to thousands of people but it is very possible. Second pre-ejaculation (pre-cum) is actually very potent, in some cases its more potent than ejaculation. So the pull-out method is a horrible metod for birth control....for all you ladies that think you are getting away with this metod you're wrong! I knew several girls in high school that got knocked up that way. And another bit of information you can have all the signs of symptoms of being pregnant and not be. This is actually a condition that a lot of women get all over the world. And I can back all of my information; my bestfriends sister is a nurse and I have read enough and taken enough classes to know what I am talking about. So yes you could very well be pregnant and you should test yourself if you haven't already. Good luck!
