stopping by pill. help!

I've been on bc for 3 months to regulate my period. I had a period 2  weeks ago and I have a new one now! (I took 2 days of pills too late) I'm still on bc but this is my last week. (I already have an para guard iud). This isn't breakthrough bleeding because it's been going for 7 days already. Should I not stop my bc yet? Is this normal? Will my planned period come in a week from now? Because sex would be nice . :/
