Thanks for all your responses.
I had a suspicion that there was a relation. Near period time, I get so wound up, I call it "peaking". Also, I asked my Doc about the irregular periods and he said that there was a definate connection between your periods and stress. Since we feel very stressed when we have anxiety, it could be a contributing factor. But it's good to know what is causing the weird cycles.
