Is the pregnant permanent or it has something to do with the ending?
What happen if all the girl are pregnant?
Is there any tricks to make more money?
Increase the charm is so hard like you need to go to the nightclub like everyday to get 3 charm,does anyone got some trick to gain charm without going to nightclub everyday?
Pregnancy is as of now permanent and will only resolve itself in an ending (so far only for Sasha, Bree, Samantha).
If all girls are pregnant then they will take up more of the screen.
As in real life, you make most of your money by "honest" work. Promotions will significantly raise the amount over time though, but except for special occasions you will probably best do the daily 9 to 5.
Charm can also be gained by books (once in a while), by suntanning, getting a haircut in the mall (again once in a while) and - with variance due to RNG - by buying the "charm machine" in the electronics store. This game however is in it for the long haul, so everything will take its time, do not expect to be "maxed out" at the end of summer or similar.
