Just a thought, but is stress an issue in your life right now?

The way I understand it, ovulation can be put off by stress. If ovulation is delayed, your period will be, too.

But, I'm not a Dr. either. I would also suggest seeing a Dr. if you're concerned.

Sorry, HappyA, I have no answer for you. I tried that route once, but it didn't work for me. Just set my cycle into continuous bleed -- opposite of what I was looking for!
