Congratulations on approaching motherhood!! Oh my god that is so exciting and heartwarming to read - I love hearing success stories when infertility has been in the picture! How wonderful

(I am v broody at the moment, can you tell

)
Regarding your therapy - do you have to finish for definite? Have you agreed a date?
I agree with SnakeCharmer that all new mums need to be kind to themselves, and remember that they need and deserve good support, even leaving out pnd.
