Welcome to week 12 of your pregnancy! This week, your baby is as big as a plum. Here’s what else you can expect this week.

Your baby

Your baby is approximately the size of a plum and is still growing at a very fast pace. Most of the vital organs are in place and functioning, and the tiny heart is beating really fast, still about double the rate yours does. Your baby can now make movements, although you won’t feel them yet. Facial features are becoming more defined, and their unique fingerprints are forming.


You’re probably going to have your dating scan in or around this week, when your obstetrician can tell you a more accurate due date. At week 12 of pregnancy, morning sickness can still be present in many cases, but it typically starts to lessen around this time. If it doesn’t for you, check in with your doctor about it just to see if anything can be done to ease the nausea and other symptoms. Fatigue may persist, but some may start to feel more energy. Around week 12, you’ve probably shared the news of your pregnancy with others, so enjoy what can be such a lovely moment in pregnancy.

Anything else?

Keep an eye on your diet and vitamin intake. A balanced diet with adequate folic acid and iron is essential for both of you. Staying hydrated and getting enough rest are equally important. It’s a time to take care of yourself when possible, as you’re nearing the end of your first trimester.
