I want to stand up and cheer for you, you are so right to put a stop to having sex until marriage, as we all know men rarely marry an easy women, also do not forget that education is a most-important part of your life, and, you really need it nowdays if your boyfriend loves you he will wait if he does not he is not worth it belive it or not i was young once, but i waited until marriage times were different when i was young and we were kept busy doing chores luck jo
it's not entirely impossible but it's highly unlikely. unless your period is late i wouldn't worry about it.
