How do you know if your sim is pregnant on sims 2 ps2 after you get abducted?

Well, If you've already tried (I'm answering myself lol) and you heard the rock-a-bye baby chime, your pregnant and also your sim will throw up and have a slight bump, and if you wanna try again because you don't no she's pregnant, It won't say woohoo or try for a baby, and your sim will have to wear different clothes, Hope this help!!!
