What if you have had PMS symptoms for a couple of days then all of the sudden they stop on the morning you are suppose to start your period but there is still no period?

I had the same thing happen to me. I'm now 9 days late and not pregnant. I went ahead and called the Doc to see what was up and she told me that I probably didn't ovulate. I'm very regular, but she said sometimes your body will just do that. I'm going to wait another week and if I still haven't started, she's goign to give me a prescription for progesterone (sp??) in order to have a period. Never happened to me before!! and I'm 26! Weird! Everyone's different though. If you know you aren't pregnant, I would call your doc.
