no condoms..

I have been on the pill for 4 months. I never miss a pill and usually take them just a couple of minutes late and that’s it. My bf and i have been having “unprotected” sex, but he always finishes outside. I started my “break” placebo pills 3 days ago. yesterday i was cramping and spotted but no period.. is that normal?🙄😭😭 It says on this app that my new period will start in 3 days. Im having thick yellow mucus..
