我怎么没看到lz说她吃避孕药那句。。。。我觉得应该试避孕药的问题。我以前也吃，前三年都没事，后来就乱套了。换了3回药也不是很稳定，后来就不吃了。现在也不吃了，用陶陶。我觉得还是不吃的好，至少对我自己来说是这样。

怎么说呢，在这个问题上，我还真是有点迷信咱中医的精神。我老觉得靠调节荷尔蒙而营造假月经不是很自然。。。当然我是听说有人吃避孕药调理月经的，治痘的，我也听说长胖的。。。

就拿我自己来说吧，最开始吃的是brand name： orthotrycyclene low，可能拼的不对，懒得查了。low是low dose，因为light weight。这个是最常见的避孕药之一。我最开始一直都很稳定。没有任何长胖，长豆，或者消豆之类的。。。
但是大约三年以后，开始出现月经不调，现象就是来一次，拖拖拉拉半个月，然后又来什么的。而且我感觉到月经量越来越少。问西医，人家说是正常，就算来一滴，也算来了这个月。可是我听起来就感觉很不爽。 至于你bleeding，你去看医生，是有个chart的，刚刚来完period的bleeding，和mid month bleeding还有来之前bleeding都是由于不同的原因，她那里可以查出，你是low estrogen还是怎么的，会根据你的情况给你换药，加减相应的剂量。

我就是这样来来回回倒腾了三次，也不见很好。因为人家说换了药还要给一定时间去适应。后来我也是有一个月没有来，再加上我总觉得避孕药导致我乳腺增生，这个没有科学根据，就是我自己觉得。我后来就毅然停了。

到今天已经3年了。每个月都来，也挺准时的，量也适中。我的结论是：避孕药不适合我。

呵呵，不客气，我今天比较闲，虽然是准备看书学习的。。。希望我的经历对你有所帮助！

ft，月经是月经，但是你是不排卵的。所以我说是假月经。但还是子宫内膜脱落好不好。

 Withdrawal bleeding (Fake period)

When you use a hormonal method of birth control, like the Pill, you no longer have an uterine cycle/a menstrual period. This is normal; it's the way the Pill works and it lasts the entire time you use the Pill. If you use the Pill for 7 years, you don't have uterine cycles/menstrual periods for 7 years. How is that possible?

Briefly, while you take the Pill, your body hormone levels stay low and, most importantly, they don't fluctuate. The levels of Pill hormones are also pretty steady. So, since there are no longer any hormone fluctuations, the lining of the uterus stays thin.

This is very important: the uterine lining stays thin ALL THE TIME, for the entire time you use the Pill (not only throughout the month, but throughout the 7 years in our example above).

No build-up of the lining means no periodic shedding. No shedding means no menstrual period. This is how the Pill suppresses the menstrual period (menstrual suppression). [Keep this term, menstrual suppression, in mind; it's an essential term and we'll come back to it in a moment.]

What you do have when you use the Pill is a monthly withdrawal bleeding episode, or a fake period. This withdrawal bleeding and the menstrual period are not one and the same thing. Briefly, by manipulating the dose of hormones in the Pill, you can destabilize the thin uterine lining enough to cause some bleeding.

可能不至于是内膜脱落，但是内膜会出现一些异样导致bleeding。
