Romelda must have announced her pregnancy quite early? Whilst unusual it is up to her. The season is still another 4 weeks away.
There is a pregnancy policy but I can’t recall what it details specifically. It came in during CBT days when there was a pregnant player that wanted to play. I believe it gives guidelines as to when to stop playing.
I stopped after the first trimester after talking with my OB but I am far from an elite athlete obviously. Every pregnancy and Mum is different.
