Anyone give me hope?

Er

I am 3days late for AF and according to glow I am 17dpo . I had a VFL on Wednesday night and went to dr Thursday (since I had a MC 3 months ago I’m overly paranoid) their urine test was negative and just got a call back saying my beta was at 5. She said she’s calling it pregnant and I go back tomorrow for another draw....but I’m so worried it’s going to be a chemical or another MC. I do have long cycles 32/33 so not sure if I ovulated late? Of course this was the month that we stopped tracking and were just putting it in God’s hands.
