Hi everyone, how soon do you go get bloods taken after you test positive? I started testing positive one week ago and I’m only 1 day after a missed period today.

Wondering how soon to get bloods taken to see if my levels are doubling, just a bit anxious due to a CP a few months ago. My test lines on the HPT have reached a point where they aren’t getting darker (quite dark already) but the control line is getting lighter.
