Question: how to know if your sim is pregnant in sims 4?
Answer: Once the 'Try for Baby' interaction is complete, the (possibly) pregnant Sim can use the 'Take Pregnancy Test' interaction on any toilet to find out if it was successful. The test costs §15 and, if it's positive, the 'Eating For Two' (Happy +1) moodlet will appear, lasting for 24 hours.
