I am a few days away from my 19th birthday and i've been taking Yasmin since the age of 11. I was diagnosed with PCOS when i was 11 and Yasmin has been what's keeping my period regular and more or less pain free since then. In May of 2008 i was switched to the generic version of Yasmin called, Ocella and started to notice more and more symptoms and side effects. My stomach pain in the mornings grew greater by the day and when i was on my sugar pill i would gain an unbearable migraine. Thinking it was just part of being a woman i ignored it and went about my life. It wasn't until December of 2008 while out with a group of friends i came into some serious stomach pain. thinking it was just a typical stomach ache that i normally got i ignored it. when i came to be about 4 am and the pain hadn't stopped i started to worry. first thing in the morning i went to the doctor who referred me to get an ultrasound. The ultrasound showed that i had gall stones and that i should have my gall bladder removed before more complications were to occur. Being a college student only a week away from returning to my second semester i opted to wait until spring break to have the surgery. During the 3 month wait i experience extreme diarrhea whenever something was put in my mouth, extreme stomach pain, heartburn, nausea, headaches, sore muscles, the list goes on and on i felt like i had been hit by a truck every day and i still had to go to class. in March of 2009 i had my gall bladder removed thinking that the symptoms would finally stop i returned to school only to find that nothing got better. It's been 7 months since my gall bladder has been removed and i'm still having the same symptoms as before and now i've added depression, stress, lack of energy and interest and many other things to the list. I'm still taking Ocella because i've never been advised otherwise but the symptoms are taking over my life. I am a sophomore majoring in electrical engineering at college and it's just become harder and harder to focus on my work or to enjoy the aspects of college that i should be with the frequent trips to the bathroom or having to opt out of a fun activity because of stomach pain. I was wondering if anyone can help me, maybe point me in a direction where i can get better and get back to enjoying what a 19 should be. Thanks.
