I'm sorry your post has gone unanswered. I don't have much advice for you because you seem to want a child. For soneone in your shoes I would have suggested getting on birth control to try and help out with the monthy problems associated with hormone overload. But, as that doesn't seem to be an option for you, I can only suggest exercising and watching your diet. Caffeine, fat, salt and chocolate are major contributors to PMS. Definitely stay away from salt, so as to retain less water. That's where the diuretic comes into play... They should help you get rid of excess water and help with the bloating and the weight gain, sometimes even abdominal and breast pain.
Drinking lots of water (I know that seems contradictory - but it's not) and exercising is important to help with these symptoms. Staying away from refined sugars and eating healthy will also help.
Good luck! I hope you're feeling better.
