Okay, I don't get this. Last month my period came 29 days after my last period started. This month, I am on my 31st day after the last one started and still nothing. Is this an age related thing? I don't take BCP's, I have my tubes tied, so I don't know what is up with this. It seemed like I had PMS symptoms about less than a week ago, but still nothing. I'm starting to feel something is very wrong. Any advice?
