4w+6days spotting

Hey y'all. Someone please help and tell me to stop stressing. Found out last Thursday I was pregnant. Hcg level was 150. I have had some very light spotting and am freaking out that something is wrong. I have 1 child but this would be my 5th pregnancy 1 miscarriage and 2 ectopics. And now I'm finally pregnant again. I was so excited and know I am worried that I will lose this pregnancy too. I goto dr tomorrow for hcg level check due to my history so hopefully all gord well
