No pregnant content though pregnancy has been mentioned via dialogue. There is only really the start of WW cell content and the plan is for Wonder Woman to get content with the next release this year.
On a side note I found a edit of the she hulk Wonder Woman scene.

To be fair, the potential of having pregnancy content, even if only as part of the closing scenes of the game, has been discussed from time to time on the discord.
