how am i not prganant

its not as easy to get pregnant as you might think...yes, of course there are tons of people out there that get pregnant that don't want to but really there are only 4 days out of the month that you CAN become pregnant. These days usually (if your cycle is 28 days) begin counting aprox 12-14 days from the FIRST day of your LMP. SO, if you had intercourse in the few days before your period was due you were not fertile...the "egg" was no longer in the optimal position or even still in one piece for it to become "fertilized" having a baby is a lot of work and it changes everything...since this is your boyfriend and i have no idea how old you are I must say just be sure this is what you want and you realize just how much it will change before you "partake" in anymore unprotected sex....
I am 29 years old and when it comes to my son he will not let ANYONE else watch him...if i try he screams bloody murder for ever and they call me frantic because they cannot handle it...SO i really cannot do anything without him...I dont mind because I love him to pieces but these are the type of things you need to be ready for...I have seen WAY too many girls get pregnant with their BFs and their BFs take off and not help in anyway whatsoeever...theres my "preaching and my 2 cents" lol....ultimately- do whats right for you because having a baby will most likely affect your life and your life alone. Good luck and I hope you get what you desire soon :-) (you can also try Ovulation tests or charting to help determine these "fertile"days too...this is the most accurate way to find them and will increase your chances of getting pregnant sooner:) )
