<s>[INST] Hello I'm taking gynera contraceptive pills since one year but i'm having huge cramps during period and sometimes starting before period and continuing for 2 days more.Pain gets so bad i have to have injections,painkillers don't help.Is it possible that gynera is causing it,what If i  switch to less hormonal pills like Cilest?Thank you [/INST] Hello,Its unlikely that Gynera is causing this pain. You should rule out endometriosis and fibroids. Get an ultrasound first. Then a pelvic exam. </s>
