What New Mothers Can Expect In The First Trimester?

Most new mothers think they know what to expect during the first trimester. We’ve seen plenty of pregnant women in film and TV vomiting constantly and complaining about swollen feet, but that’s half of the story. Your body is changing and developing in ways you could not predict. By learning about these changes you may experience, you can better understand and care for yourself during your initial weeks of pregnancy.

At Chemist Direct, we understand that this change in your life can be stressful and we want to help. So, here’s what you can expect during the first trimester.

Your Body In the First Trimester

For most women, missing their period would be the first indicator that they might be pregnant. However, there are other telltale signs your body could be giving you. Here are some of the changes your body would undergo.

  • Tender and/or Swollen Breasts: Your body will undergo hormonal changes. This can cause your breasts to become sensitive or sore. This discomfort will likely pass after a few weeks into your pregnancy as your body adjusts to the hormonal changes.
  • Nausea: Morning sickness is a common indicator of pregnancy. This can happen at any time, day or night, and does not have to include vomiting. One of the best ways to relieve the nausea, is to avoid having an empty stomach and eat small amounts of food every two hours. It is important to drink plenty of fluids. If your morning sickness becomes severe, please contact your health care provider.
  • Heartburn: Newly pregnant women may feel more heartburn throughout these first few weeks. This is natural. As your hormone levels change, it relaxes the valve between your stomach and oesophagus. This can allow stomach acid to escape, causing heartburn. You can avoid this by changing your diet, such as breaking up your regular meals to smaller ones across the day and avoiding fried or spicy foods. You can take most antacids during pregnancy such as Gaviscon and Rennie. Always check the label first, and speak to your doctor or pharmacist before taking any medications during pregnancy’.
  • Fatigue: During the first trimester, you will become more tired. This is due to changes in progesterone, a hormone, which will make you feel fatigued and want to go to sleep. Eating well and exercising regularly can help combat this. Make sure you keep up with any prenatal vitamins and supplements your healthcare provider recommends.
  • Taste & Smell: You might become extremely sensitive to certain tastes and smells. This is perfectly natural as the hormones levels change your body.
  • Urination: During the first weeks of pregnancy, you might notice that you’re peeing more than usual. For some women, this can be the hint that they’re pregnant. Don’t worry, this is natural. Your body is producing more blood throughout your pregnancy, which causes your kidneys to clean more fluid and causes you to pee more.
  • Constipation: This is common in the first trimester as high levels of progesterone in your body will cause food to digest and breakdown slower. Changing to a fibre heavy diet and drinking more fluids can help. You can take mild laxatives, such as Lactulose if your constipation persists. If this problem persists or worsens, please speak to your doctor or healthcare provider.

Your Emotions In The First Trimester
