I had my period about a week or two ago - I started taking my pill again directly a week after I started my 7 day break. I took the first 3 pills in the pack, but then I missed the next 4 days of pills, then I took yesterday's pill. But this morning I found out that I'm bleeding as if I would be if I was on my period. I'm not worried about being pregnant because I haven't had unprotected sex - I'm just worried as to why I'm bleeding as I wasn't sure if it was possible to have another period so soon after the last.

Any answers that can help are welcome
