Period after stopping birth control


So I stopped my birth control on 7/24/21 I was supposed to get my first real period on Monday. I had brown discharge when I wipe. Then same thing Tuesday except for once in the afternoon I had bright red blood when I wiped. The next time I went to the bathroom there was a very small amount of blood on my pad. Since then it’s just brown when I wipe. Has anyone else had this? Do I track this as my period?

Monday I also had severe pelvic pain that went into my right leg and back. I took a pregnancy test today that was negative.
