Biby, what a ridiculous thing to say.... These girls are at just as much risk if being pregnant as anyone in their 20's or 30's and do you know why...because they're having unprotected sex...! Maybe they are naive but they are worried and looking for advice and your criticism and jibes are not helpful therefore if you have nothing to say to ease their concerns then why post here???? Also...cramps, nausea, hot flashes, cravings etc etc are NOT pregnancy symptoms? What planet are you on...
Girls the simple answer here is if you have unprotected sex then you may indeed be pregnant. Some of your symptoms could be pregnancy related however you are all so young that these things can happen because your bodies are still growing and changing and are therefore perfectly normal.
Basically though if you had unprotected sex around the time of ovulation (roughly 14days before the start of your next period) the risks of getting pregnant are higher. You will need to take a pregnancy test around the time you think your period is due and hopefully this can set your minds at ease as many of you may be reading too much into these signs because you are worried...
I don't want to preach but some of you are young and you need to understand more about how your body works and treat it and yourselves with respect. If you really feel ready for a sexual relationship then be safe and educate yourself on the risks and use protection. Pregnancy can be the least of your worries as STD's can leave you with health issues for life...
I know you are concerned and hope you all get some answers soon but I hope you've learned something from what is a not so nice experience.
Take care x
