I've been on the pill since the end of October. I had taken morning after pill and mistook the bleed as my period so started my pill during this. My actual period came about 5 days later. Since then I have no had any bleeding at all till now. I started bleeding yesterday, it's light-medium amount of red blood so I'm guessing it's a period? I know irregular periods are a side effect but I was on this same pill before having my daughter and never had a period until I came off and I was on it for 4 or so years
