Help ! 3 months pp

I started my second birth control pack 2 weeks ago, on the first pack I had my period every 2 weeks, but when I was on the placebo pills (last week) I was bleeding with slimy discharge & ever since I started my second pack I have not had any breakthrough bleeding is that normal? I am scared I could be pregnant I have a 3 month😳 I have also been having a lot of clearish watery/slimy discharge, I take my birth control at the same every day probably just 15 min late
