I am thinking of taking microgynon again. I have a packet that was prescribed in 2012 and still has the expiry date of 05/2016. One of the pills has slightly been exposed to air but not fallen out as they have been in a cool, dry, dark place. Are they still ok and effective to take? My first day of my period begins tomorrow/Tuesday. Also, is it safe to drink herbal teas such as peppermint, lemon and ginger, lemon and honey, chamomile, fennel? What impact does taking any laxative medicine have on the pill? Kind regards
