What happens in the first trimester of pregnancy?
What happens to the fetus during the first trimester? – The first day of your pregnancy is also the first day of your last menstrual period. At about 10 to 14 days after, an egg is released, combines with a sperm, and conception occurs. A baby develops rapidly during the first trimester.
- The fetus begins to develop a brain and spinal cord, and the organs begin to form.
- The baby’s heart will also begin to beat during the first trimester.
- Arms and legs begin to bud in the first few weeks, and by the end of eight weeks, fingers and toes start to form.
- By the end of the first trimester, the baby’s sex organs have formed.
According to the Office on Women’s Health, the baby is now about 3 inches long and weighs almost 1 ounce.

Is 1 month pregnant the first trimester?
First trimester: key stages – The first trimester begins on the first day of your last period and lasts until the end of week 12. This means that by the time you know for sure you’re pregnant, you might already be five or six weeks pregnant! A lot happens during these first three months.
The fertilised egg rapidly divides into layers of cells and implants in the wall of your womb where it carries on growing. These layers of cells become an embryo, which is what the baby is called at this stage. During this trimester, your baby grows faster than at any other time. By six weeks, a heartbeat can usually be heard and by the end of week 12, your baby’s bones, muscles and all the organs of the body have formed.
At this point, your baby looks like a tiny human being and is now called a fetus. He or she will even be practising swallowing!

When do you find out the gender?
Ultrasound Scan – Around week seven of your pregnancy, your baby’s genitalia will start to become distinct. By week 14, a baby’s gender may be revealed via ultrasound. However, an ultrasound technician might have difficulty distinguishing between a boy or a girl at this point.
Doctors generally recommend waiting until weeks 19-20 to have your anatomy scan ultrasound in order to show the correct gender. When you are at your ultrasound, make sure to let your ultrasound technician know that you want your baby’s gender revealed so they can look for certain definite ultrasound signs, such as the presence or absence of a penis.
Be mindful that even at this point in your baby’s development, an ultrasound may not show your baby’s gender with absolute certainty—especially if your baby is in a stance which hides their genitalia or if you are pregnant with twins. In these instances, it may be necessary to have a second ultrasound performed.

Do you need to rest in early pregnancy?
Is it normal to feel tired in pregnancy? – It’s common to feel tired, or even exhausted, during pregnancy, especially in the first 12 weeks. Hormonal changes at this time can make you feel tired, nauseous and emotional. The only answer is to rest as much as possible.
Make time to sit with your feet up during the day, and accept any offers of help from colleagues and family. Being tired and run-down can make you feel low. Try to look after your physical health – make sure you eat a healthy diet, and get plenty of rest and sleep. Later in pregnancy, you may feel tired because of the extra weight you’re carrying.
Make sure you get plenty of rest. As your bump gets bigger, it can be difficult to get a good night’s sleep. You might find that lying down is uncomfortable or that you need to use the loo a lot. Feeling tired will not harm you or your baby, but it can make life feel more difficult, especially in the early days before you’ve told people about your pregnancy.
