Hey guys, I have been having sex with a condom and we're very careful, even to the point of checking it by filling it with water to see if any holes or anything has occurred. So I am very careful when using one, however my period was meant to be here 3 days ago and it has not arrived. I am very stressed out due to exams and my period not arriving and sometimes I can feel period pains. Also near towards my period my discharge is quite heavy however this is not the case.
