Bleeding/clots

Hi ladies, so I’m 6w1d with my second LO. And I started to have brown discharge on Friday (5w6d) and called the DR and got hcg checked and said it was normal, but for me to come in Monday to get it re checked. I’m still bleeding with dark red/brown with clots. Only mild cramping off and on. I’m trying not to over worry. My first pregnancy went great aside from hypertension towards the end. And words of advice or to help me not worry too much.
