😞 is this normal?

So I’m in my first trimester. I went in to the ER on the 21st and then again on the 24th. They confirmed my pregnancy test on the 21st and said that they didn’t know where the spotting I saw came from. I went home on pelvic rest and lost hours at work which, fine no big deal my baby is important enough to stay home. The spotting went away, until the 24th. That morning I peed as I whipped there was pink spotting and the second time I whipped it was brown instantly. I waited it out for a few hours and went back to the ER. That doctor was going on and on about miscarriage, this percentage of women at this gestational age have them and yadda yadda yadda. I’m still spotting. This is my second pregnancy however this is my first one that’s gotten this far. On the 24th it showed I was about 6 weeks with and abdominal ultrasound. My HCG levels also went from 4,000 something rather to 13,000 something, in just that short span. My OB went over everything and said she’s unsure why the hospital listed me as a high risk pregnancy because everything seems normal. I just can’t get over this spotting. It scares the daylights out of me. Has anyone gone through this in their first trimester as well? What are some things you did that kept you calm in this situation?
