Anyone else experience blood tinged discharge?

L🌝🌸

Hi! I’m 17 and a half weeks. Last week I noticed some blood when I wiped and went to the ER, they found babies heartbeat and examined me and said everything looked fine. Now I keep having blood tinged discharge when I wipe, it’s not every time but I had some a couple of times yesterday and then today? I don’t want to keep going up the maternity ER section and wasting people’s time if it’s nothing. Is anyone else having this? X
