Bleeding after period

I started my period on November 22 and had sex every day starting Tuesday the 24 all the way till the 29.My period was a lot lighter than usual and ended on Saturday.Today on the 30 I started bleeding again which has never happened.I'm on Junel birth control.Last month I missed the first three pills in my pack.We had a pregnancy scare last month because of that too.I took the test on the 22 and both were negative.My boyfriend cums inside me only when I'm on my period.What does it mean since I started bleeding again today but ended my period on Saturday?Please help!
