worried i might get preg.

hiya everyone, and before u read on i would just like to point out tht i am not one of those slapper girls or anything like tht u hear in the newspaper. anyway i think it was last monday i lost my virginty to a boy i had known all my life ( coz he n my bro grew up as freinds) he fingered me b4 he inserted his penis. i was on top,n i gave him a blowjob too, at the time i thought he was wearing a comdom, but i wasnt sure so i asked him about it tht night on fb, he said he wasnt wearing one but he withdrew b4 he cummed, i told my bro and he explained to me about precum,and tht their is a small chnce of me getting preg...but am not sure,the guy for some reason has blocked me from his fb and he wont reply to any of my msgs.

the problem is i dont really pay attention to when i start my pms and when it finishes so when i miss a pms thing i wont know.and i felt like i was going to be sick midayish tody. and i hvnt got a id so if i did wnt to buy a preg test i wldnt be able to coz of tht, n i am not sure how long i shld wait b4 considering tht i might be preggs,

plzzzzzzzzzzzzzzzzzzzz help. anyone on facebook add me and send me a msg explaining tht ur from here n wht ur veiw on it is,
