Hi, I am 23 years old and got diagnosed with pcos last January 2017. My first doctor said I need to take Metformin and been taking the medicine for a month but after a month, I still did not experience menstruation. My last menstruation was last Aug 2016.I went to another doctor and she told me to stop taking Metformin and prescribed me to take Duphaston instead for five days. She also told me I will have menstruation within 14 days after taking the medicine and need to get back to her as soon as I have menstruation. My concern right now is, after taking the medicine yesterday, I started experiencing lower abdominal pain whenever I urinate and I am feeling weak, dizzy and bloated. Is this normal? Should I continue using this medicine?
