I'm 23, I have one child. After I gave birth, my sex drive decreased. I especially have a decrease drive during my "fertile period". Why? Ttc also!
Decreased libido. Women's sex drive is more linked to the emotional state than man's ..... If you feel like you are not loved, respected, like you are not able to communicate with your partner...

No one can answer. Possibly there is no answer. I doubt that there is a physiological reason. Perhaps there is a psychological complication standing in the way of your ttc.

Therapists can be great supporters & helpful listeners.
