low hcg/unsure of LMP due to prev miscarriage

hana

Hey girls, so it turns out i am pregnant after all, even though i was testing negative at the doctor’s/planned parenthood. however, my doctor ordered a blood test and first one was 23 HCG second test (2 days later) is 64 HCG. she wants to test me weekly until we see a fetus in an US.

my question is should i be concerned about the small numbers? idk when my LMP is because i actually was pregnant last month, then had a miscarriage at 5w+1, bled from march 12-19 and tested positive again at April 8 with a frer and cheap tests too (but i was having symptoms since the thursday before that), so i didn’t have a period in between. for all purposes, my doctor is counting my LMP as march 12, which puts me at 4 weeks, but no clue on when i might have ovulated.

any guesses on when i ovulated, or how far along i am? my doctor said she won’t know until we have the ultra sound. i’m scared of another miscarriage :/
