If not, try again! How to Know Your Sim is Pregnant
You need to get abducted and hope that your Sim returns pregnant. This is the only way to get pregnant by aliens without using mods. Unlike in The Sims 2, stargazing is not necessary to be abducted, but it does help! Stargaze through a telescope (additional +13% chance) and/or have space rocks in your Sim’s inventory (additional +38% chance). To get your Sim abducted by aliens, go outside between the hours of 12:00 AM – 3:00 AM. But for the sake of completion, we’ll cover it briefly. I have an entire post about how to get abducted so I won’t go into too much detail here.
When young adult, adult, or elder male Sims are abducted by aliens, there’s a 33 percent chance they’ll return pregnant. See the mods section at the end of the post for more information. There are mods that allow females to become pregnant from abductions, increase chances of pregnancy, etc. Please Note: All information below assumes you are NOT using mods. In this guide, we’ll cover all aspects of alien pregnancy in The Sims 3 – from how to get your Sim pregnant to giving birth to your alien baby. But because there’s so much to it, I thought the topic deserved its own post. I talked a bit about alien pregnancy in that guide. Last week, I wrote about how to get abducted by aliens in The Sims 3.
