Birth control (female)

Any form of birth control will cause stagnation from a Chinese Medicine perspective and only some forms of IUD are not hormonal based so you will have to research your options well with input from your physician. I recommend you spend some time on the internet (not always a good idea, I know...) reading peoples experience with IUD. They are generally all over the place, but many women do not have a good experience. Personally, I spend a fair amount of time working with women to resolve their underlying issues and getting their IUD's removed as they have more problems with the IUD than without. But my bias, of course, is that people come to me when they are having issues. It is, however, a decent option for BC but I certainly wouldn't say it is safer. It is a reasonable option for people that either cannot remember to take birth control pills or cannot tolerate them and for the forms of IUD without hormones it may be better for your body.

Overall, I would recommend that you have acupuncture to straighten out your menstrual cycle and hormones now, then a natural method would be more useful to you. Acupuncture does a fantastic job working these issues out. You will feel better now, can avoid an IUD and other hormonal forms of BC, and quite possibly avoid a lot of problems that are bound to happen at menopause if you go into that time period with long-term hormonal imbalances.
