Yeah, period’s a bitch. In case men are also allowed to comment on what they found here are some things I researched for this exact question. As far as I can tell there are none of these brands you mentioned available in Taiwan. But… Those pills are not rocket science, so there are many pills with the same ingredients sold under multiple names. So finding one with the same ingredients in Taiwan should be possible.
Lybrel, Amethyst = levonorgestrel 0.09mg, ethinylestradiol 0.02mg
Lutera, Orsythia, Sronyx: Levonorgestrel 0.1mg Ethinylestradiol 0.02mg
Altavera, Camrese, Amethia: levonorgestrel 0.15mg, ethinylestradiol 0.03mg
Note: Camrese and Amethia additionally have a second pill type with only ethinyl estradiol 0.01mg. 7 of these special pills are taken after each cycle of 84 standard pills.
So, my findings in Taiwan:
BAYER Microgynon 30 is available in Taiwan and dirt cheap (a bit over 100NT for 21 pills). It’s levonorgestrel 0.15mg, ethinylestradiol 0.03mg. That is the exact same ingedients as for example Altavera, so it should be possible to be used as replacement. So what I do (well, not personally… But you know what I mean) is to buy Microgynon 30, but use the usage instructions for Altavera.
One thing I just started to look into is the latest developments in UK. No, not the brexit comedy, but the recommendations regarding the pill. Maybe it’s possible to use any pill continuously, for example one that one already knows to have no undesirable side effects on oneself:
