Worried or Chill

I went the the ER 3/16/2019 they told me I am exactly 6weeks and 1 day at that time, I only went in because I was spotting first it started off pink with 3 dots, it only comes when I pee. Now it comes out brown, I don’t have any cramps or mild cramps or cramps period no other symptoms I’m not stressing at least I don’t think I am; it’s been 4 days now and I am 6weeks and 5days I’m a little nervous as this being my first time pregnant 🤰🏾 but the er told me that it was a threatened miscarriage but the report basically states that everything is perfectly fine, I’m just really concerned about the spotting I have a follow appt. Friday but it seems to far away and I’m scared and nervous... should I be worried or just chill?
