I may be really stupid but i had 7dpo bloods done on wed to check progesterone and my doctor did beta hcg too which came back at less than 1 (i wasnt expecting positive at 7dpo anyway). Im guessing that this means my baseline hcg is less than 1 when im not preg....i know some people have anything up to 4....so does that mean even if implantation tokk place day 8/9- realistically speaking if hcg doubles roughly every 48 hrs it could take go like this- 1 on day 9, 2 on day 11, 4 on day 13, 8 on day 15, 16 on day 17, 32 on 19dpo....surely this cant be right-barely anyone takes that long to show bfp (myself included!). Maybe it rises faster at the beginning? I dont want to keep wasting expensive tests (im 10dpo today and nothing) but i am supposed to start progesterone if i get a bfp. Is there a point in me testing again tonight/tomorrow?
