My T was pregnant few weeks when I got into therapy. I was pretty sure about it 3 weeks in, more so bc of her reaction to some maternal topic. Then week 5 of my therapy it was obvious physicaly too and week 6 she told me. It did not really affect our sessions as far as I know and she was just normal T. Now she is on 4 months maternity leave and that is hard. I go back in November.
