Pregnant after miscarriage

I recently had a miscarriage in June. I was almost 10 weeks and had a missed miscarriage. I had a feeling I was pregnant again in August but then had an awful period my dr. Said not to worry about it. I'm now pregnant again 5weeks and a few days I called to make an appointment to hopefully get some blood work done but they don't think it's necessary. Any advice on easing your mind after pregnancy loss??
