I got a “period” yesterday that was heavy and literally only lasted a day. I’m not scheduled to get another period for 10 days. I though maybe it was implantation bleeding but everything online says it should be light bleeding and it was pretty heavy (went through 3 tampons). I’ve been on the pill for 3 years so I don’t think it could be a hormonal thing. And I haven’t had any pregnancy symptoms. I was just wondering if I should be concerned or if this has happened to anyone else?!
