Birth control- femhrt

Tory

So I started this birth control 11 days ago and I missed one day and started spotting but stopped. I'm cramping really bad. I'm not sure when my period should start because since June it's been a bit crazy. When I was on micronor back in may I always started at the end of the second week of my birth control.

Is it normal to spot when you miss one pill and then get period symptoms?
