TS, I've got opposite problem from you. Imbalance and no cramp. (Unhealthy).

Perhaps, try LD-Venus Gold by Elken. It helps both ways. Its main purpose is to relief pain and regulate hormon. I'm planning to take it soon. It will be very costly (>1k) but I don't mind taking the risk as this isn't medicine. Its all natural ingredient. It won't cause any harm to all walks of life except for pregnant mother. Moreover, I'm currently taking their spirulina. (It works wonders).

Yes TS, spirulina in itself helps but for long term. Beware do not fall for those hoax people selling. Only get from those known names.
