is it best to be honest with my gp?

my gp has just sent me a message asking about “what hormones are you taking and who prescribes them” the day after i have taken my last blood test.

i’m pretty sure we discussed this when i first asked for a blood test, but i doubt he remembers and i’m scared they’re going to stop letting me get my blood tests (which i need) through the nhs.

is it best to be honest?
