Hi.. I am 31 and i have been on this pill for 3 months now. I did not know until now that these pills are developed for low periodic cycle. My main concern was the mood swings my previous pill was causing. May be i am the odd one out but i have had no side effects of this pill and that is the reason i have joined the 24$ program too. My previous birth control pills had me getting angry and upset without any reason and crazy headaches. But they have sincerely stopped since my doctor gave me free samples of this pill. Maybe its just that the pill affects different people in different way. So far my experience with this pill has been great.. i don't have my mood swings anymore and my periods are for 3 days only.
