you could also try Vitex...it's an herb highly prescribed in Europe to regulate a women's cycles and help with PMS. It's slow acting so it can take a few months to kick in. It's worth a try though...I've heard of many women having success with it and becoming pregnant after taking it. I've been taking it for 2 months and still have very long cycles so I'm going to try acupuncture, but I'm still taking Vitex for now as it does take time. I'm hoping it will kick in soon for me!!
