  • The moment you realize you are pregnant a life is growing inside you, a wave of different emotions surely washed over you. Happiness, excitement, and relief, especially if you’ve been trying to have one for years, and maybe just a little bit of worry with this new journey you’re about to take.

    Whatever feeling you might have had, we’re here to help you navigate this latest phase: Motherhood! The first step is getting to know your baby, or your fetus at 1 month.

    Baby development at 1 month

    At this stage of pregnancy, an ultrasound won’t show you much, but you might be able to get a positive result when you take a pregnancy test. That’s because it usually takes three to four weeks for the human chorionic gonadotropin (hCG) — the hormone detected in a pregnancy test — to increase enough in your body and be detected.

    Once the sperm fertilizes an egg, it will rapidly divide while it passes through the fallopian tube to the uterus. Then, implantation will happen: the fertilized egg (called a blastocyst) will attach itself to the endometrium.

    A little bit of spotting — called implantation bleeding — is normal. This is caused by the embryo burrowing into your uterine lining as part of the implantation process, says Parents.

    After the blastocyst implants itself into the uterus, it will divide into two. One part will form the placenta, which is responsible for transferring nutrients from the mother to the baby and also transfers waste from the baby. The other part will develop into the embryo.

    From the time of conception to the eighth week, your little one will be called an embryo. Then, it will be called a fetus until the time is is born.

    At this point, the sex of your baby will have been determined — one of the first things that are formed once the sperm meets the egg is the genetic makeup of your baby, which includes their sex. Inherited characteristics like their eye and hair color, skin, and body type are also set at this stage.

    What does my fetus look like at one month?

    According to Parents, three “essential cells layers” are developing during this phase. One is the ectoderm, which will eventually turn into your baby’s nervous system, hair, and skin. The second is the endoderm, which develops into the gastrointestinal tract, liver, pancreas, and thyroid. Last is the mesoderm, which grows into the baby’s skeleton, connective tissue, blood system, urogenital system, and muscles.

    At four weeks, your child is still a ¼ inch embryo with an itty-bitty face and large, dark circles for eyes. According to WebMD, it is developing the structures that will eventually become the face and neck. The placenta, lungs, stomach, and liver will also start to develop.

    “The mouth, lower jaw and throat are developing. Blood cells are taking shape, and circulation will begin. The tiny ‘heart’ tube will beat 65 times a minute by the end of the fourth week,” says Cleveland Clinic.

    At the end of the first month, your baby will be around ¼ inch long — almost the size of a grain of rice.

    Does the fetus already have a heartbeat at first month?

    Fetal heartbeat may be detected as early as 5 ½ to six weeks after gestation, according to Healthline. But it is best to wait at least 6 ½ to 7 weeks. Your doctor may schedule an ultrasound around this time to check baby’s healthy development.

    How to care for yourself and your fetus at 1 month

    If you suspect that you are pregnant and it’s been a week after you missed your period, take a pregnancy test. A doctor might also ask you to get a blood test as it is more accurate.

    Schedule a prenatal checkup as soon as you get a positive result on your pregnancy test. If you’ve already been taking folic acid in preparation for a baby, just continue taking them along with prenatal vitamins. Your doctor will prescribe these if you are not taking them yet.

    Be gentle on yourself — even if your pregnancy is progressing normally and you don’t feel any pregnancy symptoms, allow yourself a few breaks every now and make sure to get enough sleep and rest.

    This is just the first month of your nine months of childbearing. Remember to keep making healthy choices because your body isn’t just yours anymore. It’s now your baby’s, too.
