Pregnancy after miscarriage no period in between

LADIES!!!!! I had a mc last month and was only 6-7 weeks along. But just found out via. Blood test that I am pregnant again!! I’m sooo excited but also very anxious because I didn’t get a period in between. I’ve been told by friends that I’ll probably mc again because I didn’t give my uterine lining enough time to build back up and now I’m freaking out. Any words of encouragement or facts or has anyone experienced this with positive results???
