Is reproduction completely off of the table since the patch?

I read somewhere that the newest update has completely messed with the pregnancy element of the code - so the team are having to re write the code so it fixes that as well as fix the newest patch! 

I've had to do pregnancies via science because my sim is currently in the first trimester (visibly so) and she just wont progress, even after exiting, reloading multiple times and has no pregnancy buff and is constantly throwing up poor gal!
