I have been on the pill for 8 years and have decided to come off it for various reasons. It has been such a long time since I had a proper 'period' that I am unsure how to calculate when my first 'real period' will arrive. I am aware it may take a while to get back into a regular cycle. Prior to going on the pill they were usually every 28 days but due to suffering with eating disorders they had become irregular in the few months leading up to when i started the pill. Do I count 28 days from the last day I took a pill or do I count from the day my withdrawal bleed started after taking my last pill? Any advice is gratefully received.
