Ok sooo...

Soo I went to the ER with bleeding, I bled for about two days. The ER said my hcg was only at 7 so they considered it a threatened miscarriage because they didn’t know if my levels would go up or down. So I followed up with my OB and they said I had a miscarriage based on my levels but they never checked them again. No blood work, no office visit nothing. So now I’m paranoid that maybe I was still early that’s why my levels were so low and some people do bleed in the beginning. What if I’m still pregnant ? Has anyone had this happen to them
