 [ Symptoms ] can skin become sensitive when it was not before [ Disease ] hi having any kind of unprotected sex is always a gamble it takes just one sperm and that is all its takes out of millions ok it could be from stress that is causing her not to have a period and it could be just a skipped or missed period who knows the only real thing she can do is get to her doctor in a weeks time and get a test done there if she finds out that she is not pregnant then get her to ask her doctor about bc but please not depo shot just to many bad side effects hope this helps you both good luck
