I have been on Loestrin 20 since the beginning of summer 2011. I had recently stopped taking the pill for a full cycle because I went on holiday and forgot my package. Last Friday I started my period and so began taking my pill again. My period usually lasts only 4-5 days and has ONLY gone over that time once before while on the pill. My period has been here for 8 days now and it's a little worrying. Please help
