Spotting concern

Hi ladies. I miscarried about 4 months ago and got my 🌈BFP 🌈about 2 weeks ago.

Since I MC prior to this pregnancy, my doctor sent me for bloodwork immediately. All my levels came back great which is totally different from last time. Last time my progesterone was extremely low (5.6) this time it’s at 17.5

And my hcg doubled as it should. 2 days ago I spotted brown in the AM, but it never came back. Well this morning when I wiped I saw this and instantly panicked! I called the nurse as my doc is currently out of town this week and she said unless it’s bright red blood not to worry but just to monitor it. Although this is not “bright red” I feel like it’s reddish/brownish and am just paranoid I will MC again. I know spotting in early pregnancy is normal (I’m only 6 weeks today)

But has anyone else had spotting like this and had a viable healthy pregnancy?!?!? Thanks in advance! Btw this only happened this AM and hasn’t come back
