Hello girl, i'm having thesame problem. I'm sexaully active since 3years.
Have got boy friends, had sex without any protection; yet I have never been pregnant
i'm now with my boy 10months now , I love him like crazy and really wanna make a baby. Yet not getting pregnant
lately I thaught I might be pregnant but nothing. I went to my doctor who advice me to quit smoking . You are not infertile, you're still very young ,getting pregnant is really a game , and remember the most fertile couple has got 20per, chance of having a baby each month so just be patient.
