Yes in the UK, my clinic does hcg bloods. I had one 3 days after my positive test last year but unfortunately that ended in a chemical. Just wondering if it should be done sooner
I don't see a benefit in doing a quantitative hcg earlier, it doesn't matter what day you do it on, just want to see it rise over the following 48 hours
If you are in the UK you are unlikely to have a HCG blood draw. They would just book you in for a 6-7 week scan.
