Help please

So the 29th of May I was supposed to get my period but I skipped it because I was going to pool party this weekend. So when the sugar pills came that day I immediately started my next pack of pills. Today June 14th I’m witnessing some type of bleeding.. so I don’t know if it’s from skipping my sugar pills. The end of this month I should get my withdraw bleeding.

If someone could please help me understand why I’m bleeding in the middle of the package? That would be great!

Also my boobs are very sensitive (I have not missed any active pills)
