you know you could be pregnant, its quite a high possibility if u have unprotected sex. BUT saying that, if you look at all the people on here who are trying for a baby, it takes them more than a week to conceive, sometimes months or years of unprotected sex. then again, some girls get pregnant the first time, it all depends on ur own personal fertility…the only thing u can really do is wait and get a test.
let me know, good luck and plz dont worry yet xx
