I am on the pill and have been VERY consistent with my period since starting the pill a year ago. Last weekend I forgot to take it, both Saturday and Sunday, so I have had a light period all week. According to the nurse I called and talked to last week it’s pretty normal and can last a few days. This happened one other time because I was sick and I just didn’t take my pill and let myself have my period then started it back up and my period stopped. This time however my nurse told me to continue my pill as normal. Tomorrow will be a week since it started, when do I need to be concerned?
