Hey I have always been worried about pregnancy since a close experience a while back and now I am worried again. Today is my girlfriend's 28th day in her cycle and her period still hasn't come. She says she feels all the symptoms and thinks it should be soon but i'm not too sure. Can anybody help me out and tell me what signs I should be looking for and how long should we wait until she is "late", a week 2 weeks or what? If anybody can post thoughts on this I would greatly appreciate it.
