Fear of miscarriage 😔

I had a positive test done 3 days before af was due 6/9. I had some mild bleeding about 10-12 days before af. It lasted about 9 days. What I mean by very light, I could only see it when wipe and sometimes in the liner. It's been very light pink and then it turns brownish. It stopped for a couple of days and then it started again 2 days ago. I'm afraid Of misscarriage because I've been TTC for a lil over a year. Is this bleeding normal? I will call for an appt tomorrow, but in the meantime I'm just stressing over losing my much awaited bump 😞
