Concerned

So today I was supposed to get AF but it never happened. I usually am on time and never late. I am worried that it is something serious do to my pelvic pain I was having since the eleventh but when I went to the doctors all my test came back normal. I am pretty sure they didn't test me for being pregnant because they never did blood testing. But I am really scared because I have no cramps at all and no symptoms of AF. Could it be something bad?
