i was diagnosed with PCOS and have been using ovranette pill for the past 1 year for irregular periods. Recently for the past 2/3 days i have been getting abdominal pain and nausea. Today the nausea had stopped but the abdominal pain is there. i am due to start my period in 3 days and i have never had this pain before. IS it cause my period is due or im pregnant that im in this pain??
