I finally got my new sim abducted and pregnant. He just started showing and he and was a little low on fun and wanted to "stargaze", so I start doing that only for him to be abducted again. I figured it wasn't a big deal, but he just did the little animation where he would normally switch into maternity clothes even though he's already in them.

Has this happened to any of you? Should I be worried? I'm not sure if he can afford a second child, his rent is kind of high.

I don't think he can be pregnant twice at the same time. It might have reset the pregnancy flag though and you may have to wait three days from the second abduction to get the baby.

I've never had a Sim who was alien pregnant before. Boy are you lucky!

Back to your question: No he won't have another baby inside. It's like...when your female Sim is pregnant, she can still WooHoo on the 2nd trimester, but her children won't double at all. Trust me, I've tried.

Well, he could have twins. But it is not because he was abducted twice, it is just the chance.
