Trimester 1

Welcome to the first trimester of your pregnancy. We've compiled some handy information about how your little one is growing and what you, as a mom-to-be, can expect during the first trimester of pregnancy, plus some tips to keep in mind during this important period.

Your Baby’s Development in the 1st Trimester of Pregnancy

During the first trimester of pregnancy, what starts as a tiny bundle of cells is quickly turning into a fetus that's about the size of a large plum. In these first trimester weeks of pregnancy, your little one's heart, lungs, liver, spinal cord, head, and tiny limbs will form. Meanwhile, your uterus is fast becoming a comfortable home. By the end of the first trimester of pregnancy, the placenta and umbilical cord will also be in place.

Some exciting milestones in the first trimester of pregnancy include week 9, when your little one may start moving around (though you won't be able to feel these movements until the second trimester), and week 11, when your little one's heart is beating loud enough to be heard at an ultrasound scan. By the end of month three, all essential organs and body parts will be in place — albeit in teeny-tiny size.

1st Trimester Pregnancy Symptoms

Are you experiencing any of the typical first trimester pregnancy symptoms but still not sure if you're really pregnant? A home pregnancy test can confirm your hunch, and you can head to the doctor if you're in any doubt. You'll probably be curious about when your baby will arrive, so take a look at our handy due date calculator tool which will help you find the estimated due date.

Some moms-to-be find the 1st trimester of pregnancy quite challenging. You could be in for a ride on an emotional rollercoaster, as well as dealing with some annoying first trimester pregnancy symptoms like tender breasts, constipation, cramps, and frequent urination.

If you experience nausea or “morning sickness” during the first trimester of pregnancy, you can think of this condition as a reassuring reminder that you are expecting a baby, while also trying to reduce the symptoms of morning sickness with some simple strategies. You might also notice some pregnancy cravings for unusual foods. Weird as they are, these are usually nothing to worry about.

What to Keep in Mind for the 1st Trimester of Pregnancy

What you’re eating during 1st trimester of pregnancy will naturally impact your growing little one, so it’s important to follow a healthy and nutritious pregnancy diet. Consult your healthcare provider about taking folic acid and prenatal vitamins. Learn about what is safe to eat and what isn’t — undercooked shellfish and unpasteurized cheeses should be avoided, for example. Alcohol, smoking, and drugs may be harmful, so it’s best to steer clear of these. As for those life-saving coffees (and chocolate bars), the recommendation is to limit your caffeine intake to 200 milligrams a day, the equivalent of a 12-ounce cup of joe. Have a look at pregnancy diet tips to help you maintain a balanced diet between you & your baby.

The first trimester of pregnancy is also the time to find a good healthcare provider who can help you throughout your pregnancy and during childbirth.

Feeling exhausted? Try to relax and get plenty of rest in these early days. Building a new life takes a lot of energy. And, you've got two more trimesters to go before you'll meet your baby.
