a friend of mine takes a product called Health comes first 3-in 1capsules can be bought in Wordwide house in Central, she said made her mestruation more regular and relieved menstrual pain
The best idea might be to have the cause of the irregular periods checked out. The endocrine system is very complex and many different issues can cause these problems. I personally suffered for many years from bizarre symptoms and then after 3 years and 4 doctors had a benign pituitary tumour diagnosed.
The previous doctors just dismissed it as nothing to worry about and I should count myself lucky to only get one period every 2-10 months...I knew it wasn't right!!!
A healthy body (as mine is now) will be regular as clockwork, so much so that you can set your calander to it!
