Why could cause me to menstruate every two weeks?

I switched between a couple different birth control pills a few months ago, then stopped bc pills completely at the end of November 2006. It took seven weeks for my menstrual period to arrive, then two weeks later I menstruated again. Now, two weeks later, I am menstruating once again with a slight sensation on my right side, like ovulatory pain. Every two weeks for the past month or so. What could be causing this? Anyone had any similar situation?Why could cause me to menstruate every two weeks?
That's usually due to ovulating twice a month. That used to happen to me for awhile in my 20's, but I didn't have ovulatory pain.
Your body may be trying to readjust from not being on the pill. You best see your Gyn for a checkup and to find out what is happening.
This could just be from all the changes in birth control and your body trying to regulate itself after the hormal imbalances. If it get even closer together than you should see your doctor.
Are you anywhere near menopause age? That causes all kinds of strange things to happen to different people.
Sometimes it can take time to adjust to being on the pill but pls check with your dr to be on the safe side to rule out stuff such as hormone imbalances.
u should go 2 a doctorthat sounds serious
for me, it was my mercury fillings. i had this happen for 20 years. i got them out and it went to normal for the first time. i had hypothyroidism, too. i don't know if you have amalgams, but if you do, get them out!
