First trimester weeks

Congrats! During the first trimester, you’re getting used to the idea of being pregnant.

Second trimester weeks

As you enter this second trimester, your body will settle down to pregnancy.

Third trimester weeks

You've reached the third and final trimester and will be heavily pregnant by now.

Week 5 of Pregnancy

If you have no period and a positive test result, you're going to have a baby!
When your pregnancy is confirmed, it's natural to experience a mixed bag of emotions-excitement, disbelief, joy, and anxiety. Everything is about to change forever for you and your partner. Give yourselves time to take in the big news. You may not feel pregnant yet, but momentous changes are taking place in the hidden world of your uterus. Step by step, the building blocks of life are being set in place.

Your baby today

The embryo seen from above now has a subtle groove (the primitive groove) and a small central depression (the primitive node), both seen here in white. These changes start at what will become the base of the spine and progress toward the head.

You're probably eager to know when your baby will be born. The chart below will tell you the expected date of delivery.

Until you have an ultrasound in a few weeks' time, your baby's due date will be calculated by counting 280 days from the first day of your last menstrual period. At the dating scan (see It's really happening!), your baby will be measured and his age calculated. The scan date will then be used since it is considered to be accurate.

While you're bound to want to know the due date, try not to get too fixated on it. Most babies are born within about two weeks of their due dates but your baby will be considered to be born at term if you give birth between 37 and 42 weeks. So your estimated delivery date is just that, an estimate; your baby may be born earlier or later.

When will your baby be born?

To figure out your expected date of delivery (EDD)-also known as the due date-you need to know when you started your last menstrual period (LMP) (see This is Day 1 of your Menstrual Cycle). Enter your LMP date here to discover when your baby is expected. For example, if your last LMP was January 13, then your baby will be due on October 20.
