After period

(Just a little back ground information)So I’ve never had a mother figure in my life so I had to figure out everything body related myself. I honestly don’t know what a normal vagina is. I assume mines is normal but recently I’ve decided to pay attention to mines more often and I noticed that after my period I would have some brown discharge which I googled and they said it dry blood, which is great but I noticed it has and odor early last month I noticed I had an odor also but can’t remember if there was discharge but I assume it is normal because I’ve been on my period/spotting for two weeks because of birth control and I’ve managed so far. Is that normal or is that an infection? Also should I start taking carnberry pills so it could smell like nothing or smell how it supposed to smell which is nothing?
