原来发的贴在下面。昨天来月经了。没有怀孕。太幸运了！7天以后一定正常继续吃。万幸万幸！
姐妹们麻烦看一下:
我交了新男友，为采取防范措施开始吃避孕药。一共吃了7天，然后第8天刚好应该是我的自然经期，我就停药了等来月经，但是第9天因为月经还没有来就爱爱了。
只要吃够7天之后，药就应该生效了。那停药的7天里（for period）应该是受保护的吧？关键是吃的时间有点短了，只连续吃了7天。所以有点担心。
如果还没有要小孩的打算，吃药不是一个最万全办法。要好好保护自己。
你是说要戴TT吧。可是我真的不喜欢TT。好吧。为了不怀孕万全起见。毕竟有了孩子太麻烦。现在时间不成熟。
亲爱的lz，你那很可能是撤退性流血，不是月经。请看药附带的说明书，有问题请教医生或护士。
还有上面提到万全的办法，万全的办法有，就是万全不要有性行为。安全套一般只有85%的有效率，药高于99%。任何避孕带来的副作用都比堕胎的伤害小很多很多。
多谢分享, 一个活生生的case study
还那么严格区分啊。应该就是月经。还有血块。怀孕没那么容易。
顶这句：任何避孕带来的副作用都比堕胎的伤害小很多很多。
但是也有可能不吃避孕药也没中。毕竟中奖率也不是那么高是不是。我是大松一口气啊！
有血块不能说明那是你的自然月经，你停药就几天，不是撤退性流血是什么？吃了药就没有自然月经。
怀孕的几率说不一定，如果不避孕，一般是80%的夫妇一年内会怀孕，90%的夫妇两年内怀孕。至于是做一次就怀的不是没有，只是几率的问题。一般说来，不要有侥幸的心理，做好防备最重要。

回答你的問題，nhs是说安全套是98％,但是那是perfect use。Typical use: 85% effective。 这个你google一下，都是quote的85％。安全套使用要求使用人非常有组织有纪律，使用时还要佩戴正确。里面包含的不确定因素太多。一般研究表明，特别的青少年，使用安全套一般是inconsistant。只需要一次不安全就有机会中招啊。
还是小心吧，避孕药吃的多了也不见得是好事
不想要孩子就带TT吧，女孩子还是要保护好自己，毕竟受罪的都是女孩子，男人又没事
谢谢你 ＝）
在找85％ 还是98％ 的时候，找到这个有趣的：
“Condom Effectiveness
Condoms are effective because they block contact with body fluids that cause pregnancy and sexually transmitted infection. Most reports of condom failure are the result of inconsistent or incorrect use, not breakage (Macaluso et al., 1999). A recent study of college students found that condom use errors were very common — 40 percent of the young men surveyed reported that, within the previous three months, they had not left space for ejaculate at the tip of a condom, and 15 percent had taken a condom off before completing intercourse (Crosby etal., 2002). In the U.S., the actual breakage rate is a low two per 100 condoms (CDC, 1998). High failure rates in some studies occur because
many people over-report contraceptive use to shift the responsibility for an unintended pregnancy to a “faulty” contraceptive. Such over-reporting artificially inflates failure rates (Trussell, 1998). Condom failure rates are also inflated because some young people have been shown to inaccurately report condom uses, use condoms incorrectly, and respond to survey questions with what they perceive to be socially desirable answers (Rose et al., 2009).
In fact, most people who use condoms do not experience breakage or slippage. Most condom failures occur among a minority of users because they are less experienced and/or less careful about using condoms than more successful users (Steiner et al., 1993, Steiner et al., 1994).
Condoms as Birth Control
Condoms are an effective, inexpensive form of birth control. Of 100 women whose partners use condoms inconsistently or imperfectly, 18 will become pregnant in the first year of use. Only two will become pregnant if condoms are used perfectly (Trussell, 2011). Unlike many other forms of birth control, condoms also protect against sexually transmitted infection. Additional advantages of condoms as birth control include low cost, easy access, simple disposal, minimal side effects, and longer-lasting sex play. Using condoms can also enhance sexual pleasure by reducing anxieties about the risk of infection and pregnancy (Warner & Hatcher, 1998). ”

我本来自然月经就是这个时间。基本不会错的。没有任何怀孕的感觉。
you got lucky this time. like I said in your previous post, read the booklet that came with your OCP carefully in the future. You have very little knowledge about birth control and that’s very scary. You may not be so lucky next time.
And I recommend you get a pregnancy test still. Like someone else said, this can be withdrawal bleeding, or worse, implantation bleed.
sorry can’t type in Chinese.
请问“安全套一般只有85%的有效率”这你是从那知道的？

是对的，药是比安全套稍微高2％如果他们都用的正确，不过安全套
tbc。。。不过安全套 能提供多一种保护＝）
