Hi Beth Iam the same as you I was on the pill for bout 5years on and off when i felt like it and I came off it nearly 6 months agao and have REALLY light periods 2 cycles ago i had really light for a day and a half and in that time I had 1 hour of it being heavey! I use to have my AF for about 14 days when i was about 15 i think cause its been so long our bodies change and its not like we are developing still and stuff. I wouldn worry my doctor said its probabley just made it better being on the pill.
