Scared

I am 5w 5d with my second baby. This morning, I woke up with some cramping and bleeding and the bleeding has continued all day today, about the amount of a regular period. I called my doctor, they sent me for bloodwork today to check my hcg levels and to have it repeated in 48 hours to compare. They said it is too early for an ultrasound. I am so nervous it can be a miscarriage. Anyone have a similar situation and everything was okay? I had some spotting for my first pregnancy, but this is more 😔
