since you are a nurse you know they cautuerize the lining of the uterus to stop menstration.
I'd go for it...
I think it is the easiest remedy for your ills, from a natural health stand point the hormones are in imbalance but the amount of rest and self care you'd need to rebalance may never occur with the demands of your busy life.

Do you drink alcohol or smoke? It may be time to quit.

I think it is a reasonable answer if you have health insurance!
Normally health insurance companies demand you take the pill to try to rectify the circumstance then take progestrone then they will consider other methods if all the others have failed
