I decided to have a break from the pill (Microgynon) which I had been on for 5 years. I had my first period on 9th Oct 2012 (4 days), I was then 2 weeks late and had my next period on Nov 24th 2012. I was due on on the 22nd Dec 2012, but so far I have had nothing (making me 19 days late). Over the Christmas period I have gained about 1/2 stone in weight and my diet has been up and down. I am having regular intercourse, but use condomns all the time. I sometimes get the symptons I do just before I come on my period, bu then it never arrives.
