Really? I thought she might convince Henry to keep trying for a son with Catheirne or something. Although I should’ve expected that (she was basically afraid of making political moves)
I don't think anyone can suggest that Catherine and Henry did not *try* for a son. She had at least 6 known pregnancies over an 8 year period and that probably overlooks early miscarriages which were not documented - it is interesting to me that between the birth of Henry Prince of Wales in Jan 1511 she did not officially conceive again until late 1512.
I don't think there is any evidence that Henry stopped sleeping with Catherine in 1518, the year of her last pregnancy.
