Well...that's a first.

My sim became pregnant when she didn't woohoo anyone.

I have my sim and her boyfriend living together. They woohooed alot and eventually she became pregnant and had twins. The day after she brought them home from the hospital I saw that she was throwing up. I was thinking...she can't be pregnant. It's impossible. She hasn't woohooed! Well to my surprise she was getting pregnancy buffs and her belly popped out. Her and the boyfriend did not woohoo since the birth. I'm perplexed.

I canceled the pregnancy and had to go into CAS to flatten her belly. I found this a bit annoying.

Any guesses why this happened?
