Hcg is bothering me should I worry

Melissa • 👼👼👼

I got a faint positive Sunday called to do bloodwork on Tuesday my levels was 9 nurse told me it was very low and after having 3 chemicals and 1 miscarriage I was scared. Went back in today and my level is a 40. Still seems low I’m about 4 weeks 5 days. I’m having a lot of mucus discharge but no cramping nor blood.
