上個月,我同女朋一時忍唔住,在無袋嘅情況之下做咗一次,之後大家都覺得前所未有咁HIGH,不過又怕有BB,雖然我地都諗住結婚架喇,之後佢唻咗M,咁就咩事都無,不過而家我地都好想唔帶袋做,但係我又唔想佢食藥,唔知安全期係點計呢,聽人講話經期前後唔知幾多日就係,咁唻經之後計係咪準D呢?

哇~~~~~~
唔好亂黎呀~~~~~:smile_42:
安全期依d野好唔準ga~~~
我之前都係咁,就日日都驚到死~
到左自己前陣子m期唔準,就去打避孕針

唔好覺得避孕針同食藥一樣
避孕針冇side effect,令經期準時黎,同會減少經痛&會prevent幾種cancer

有兩種針可以打,一種係每個月既,就會係女仔黎m個日開始計既第7至第9日打,之後每個月都一樣
每個月一百元~

另一種係3個月打一次,就$180

我依家就打每個月既,男朋友都有內射
不過我都會準時m到
不過因為我打針係m期唔準,所以我男朋友知我打完針都會陪下我
呀...係打patpat既~~~

不過都話你知啦~~~
安全期係黎m個日既前7日後7日
不過係好唔準既,因為女仔排卵時間可以唔同
所以唔好試呀~:smile_42:

Does your gf has regular period? (meaning fixed amount of days each month)  IF not, then either don't try the following, or use her shortest cycle to calculate:
Every woman has different days cycle... typical is 28, but personally, mine is 34.. so calculation is different for everyone, middle of it is the day the egg will produce.  

(Using the 28 day cycle as an example)

Day 1 is the first day of the period, Day 14 is supposedly when the egg is produced.

but sperm lasts 2-3 days ( in the body.. so we are at Day 11...

usually, you have to factor in 2 days for calculation mistakes... 

So the really safe period is day 1 - day 8. 

Day 1 - the first day of her period
Day 2-8 (safe period)
Day 9-10 (leave out for safe margin calculation) (probably not safe)
Day 11 - sperm cannot enter safely (start of non-safe period)
Day 14 - egg is produced. 
Day 14-28 (really non-safe period)

However!  Women produce these discharge, mucus like thing... (白帶), and the thickness is different throughout the cycle... about one week before the period, is when the 白帶 are thickest, so sperm cannot enter the body... (but put in 2 days for safe calculation, then we have 5 days)

if you calculate that in.... then you have about 8 days after the period (count from the day your period starts, not when it ends!!), and 5 days before the period.   so you have a total of about 12 days.   

if you are lazy, or don't want to record your period days, or don't want to do calculation, please use other birth control methods!!
