Positivity only please

So since Saturday I have noticed minimal brown spotting. I only see it when I wipe maybe 2-3 times a day. Freaked out and went to the ER they said baby was fine, hcg levels within Normal range. I’m 5w4d. I still have this going on, last night about midnight I went to the bathroom and wiped and I saw the spotting had turned to light pink; but now this morning when I woke back to brown and now nothing. Anybody ever go through this? This makes me nervous
