Pregnant or not?

I got pregnant after a year and a half trying in May. Found out we lost our baby in July at 9 weeks. I just got my first positive test since then. I was able to get blood work Friday 9/8 and they said my test was positive but my Beta is 5.36. She then said either your really early or it could be a chemical pregnancy? I know I may not be even 4 weeks because I ovulate late. I cannot get excited about being pregnant for one because of being scared of losing it again! But also because she said it could be chemical! Now I have to wait until Monday for more blood work. I want to be excited and I am still getting positive tests but I am freaking out! I need to words of advice!🙏🏼 And prayers!!
