My Sim won't stop having babies?!

Hello. I looked at your website. It seems to be though that problem can only be fixed it I am in Oasis Landing. My sims' family is in Moonlight Falls. This first happened in Oasis Landing when I got a DNA baby. They spent their 5000 simoleons and went back home with no child. They went into the hospital but then reset halfway finished. So I reloaded the previous save and traveled back to Moonlight Falls. This happens to all of the families in that town. So I tried it another way. So the lady was a the hospital and at first I thought she was just having twins then triplets, but then I was wrong. They are all boys and tried so hard to give them the same letter name. I started with the letter J. I never new there was so many male names that started with J. I tried to delete the pregnancy moodlet, but it did not work. I tried to reset the sim, but it did not work. She had so many kids that only small infants was the inhabitants of her home. They kicked their mother and father out of the house. Now my whole town is going to die out because they have too many kids. All I want is one. So I reloaded the previous save and I try it again, but alas the problem does not change.
