I took Mercilon pills for more than 2 years. not because for birth control but because i always have very bad menses cramp every month. Since 12 when my first menses came, i always have problem every month on the 1st and 2nd day of my menses. the cramp is terrible. sometimes i even need to go till the GP to get jabs to ease the pain, i cant even sleep well at all. therefore, the doc at GP asked me to take this Mercilon pills. At that time, i wasnt even married all that. But i continue to take the pills monthly coz i do not want to experience the bad pain again n again, even until i'm married, im still taking it. hmm.. coz my hubby n me didnt want a kid so "SOON" at that time, taking the pills for 2 reasons then. =) n of coz, did not conceive all the while.
It was the time of the year that we wanna TRY a kid out. so i stopped eating the pill. for the first time,first month we tried, I GOT IT! ok, in chinese saying "4D also not so accurate"! first prize! so its tested n proven on me that the pills helped my monthly cramp to reduce ALOT and of coz birth control and i did not gain weight or had any side effects since day 1 i took the pills.
when i was planning for a kid back then, i did ask my GP if i should still cont taking the pills coz i heard STORIES that the pill may affect the baby (leading to all kinds of weird illness).. blah blah.. but the GP said his wife also taking the pill and once she stopped taking, the nx month she got preg. GP say dont listen so much stories coz all not proven one. haha! =) felt relieved after that .
i last took the pills in Apr'10.. n yes, was tested positive in Jun'10.. doc calculated that i conceive in May'10. So, now relieve already and dont listen to too much stories. haha! my mother in law also shocked when she got to know the news coz she knew i was taking pills. then i say i stopped taking in May'10 loh.
hope it helps!
