Is this normal?

I’ve been on the birth control pill elinest for about 2 years. I’ve recently stopped taking them because me and my lover want to start trying for a baby. On Wednesday June 20th I stopped the pills on the last day of my period. (Which was also the day I was suppose to start my new pack) and the next day I started spotting brown stuff, and today I’m still spotting. Is this normal for coming off the pill? I never spotted after a period while I was on the pill. I thought you usually spot when you stop the birth control mid pack???
