13 weeks pregnant with brown/maroon coloured blood?

I’m just at 13 weeks and the last few days I noticed brownish maroon coloured blood everytime I used the washroom..it’s only when I wipe but it’s scaring me because my lower back just started to get like sore🙈

I contacted my doctor who hasn’t gotten back to me yet. I called a few days ago for the spotting when it started and they said as long as it doesn’t fill a pad which it doesn’t even get on my underwear.

I’m debating on just heading to the emergency room out of fear.. anybody have this and everything turned out okay??
