Pinkish brown discharge

Dallas • 💍Married to my high school sweetheart. Mother to two beautiful girls 2013/2020. 💗
Hello :) I was supposed to start my period on the 8th, I wiped and there was light pink. Usually when that happens I start the same day. In this case I didn't, yesterday was the same deal but it was mostly brown like if my period was ending. Today was the same deal, I've been nauseous here and there but nothing to dramatic. This has never happened before any of my periods. My first pregnancy I didn't have implantation bleeding. It's been three days same symptoms no period. Has anyone had this and was actually pregnant? How long did it go on for? Thanks!
