I replied in PM but for everyone in your situation, here is an update:This is my saved file as far as I've come and there is no way to see Teodora for now
It seems that you couldn't make her pregnant the second time and without second kid, she will not talk with you.
In the next update the game will give you a second chance with her to make her pregnant for second time.
Progress log 0.18.2

Teodora - (took a lot of time to code and track all logic), now you have a second chance to have a second kid if you missed the opportunity when you had sex during the night. Call her when she is ovulating.-DONE
