ADVICE PLEASE!!!!!

I'm on the pill called lolo and I just started my second pack. I was supposed to get my period when I Took the placebo pills but I'm now 6 days late. About 5 days ago I had a small amount of very thick blood, could that be my period? My boyfriend and I had unprotected sex but he didn't cum inside. I am so worried can someone give me their opinion or advice or anything... Please
