Can you advice me to reduce the pms and menstrual pains

This may seem like a surprise, but I often have VERY good results with normal Chiropractic adjustments to the low & mid-back, & maybe even the lower neck.
The entire nervous supply of the uterus & ovaries r supplied by the lower plexus of the spinal nerves.
6-8 treatments can make a huge difference, then after that once a month or so to keep u fit. Good luck. PS: Get a chiropractor from an insurance website, not the biggest ad in the yellow pages, who may be more financially motivated than concerned about getting u better.

there are many herbal methods which mainly include Evening Primrose oil, but in my experiance they ar not very effective.
i had trouble when i was younger and was placed on the contraceptive pill aged 13 (well befour i was sexually active), and it eased my symptoms dramatically.
