Hi,

I just want to ask, is there a way to make sims not pregnant in sims 4? I have sims that is not part of the household and she get pregnant, I don't know which trimester she is in but it show her belly that she is pregnant. lol. I have mod for canceling the pregnant but it say its too late for her to terminate it. So do help if there is a way for her not to pregnant. I have her sister pregnant. Not her being pregnant as well. lol. I didn't know she was pregnant.
