Your Checklist At Five Weeks Pregnancy

The initial phase of pregnancy can be a vulnerable one and would require you to take care of yourself and the little one in your belly. Here are a few tips you can follow to stay healthy.

  1. Visit the doctor: This might be your first appointment with the doctor after the pregnancy is confirmed. Your blood pressure and weight will be checked. The doctor might ask you several questions such as the date of your last menstrual period, previous pregnancies, and allergies to medicines or anything else.

They may suggest a specific diet and supplements, plus any medications if necessary, based on the information you share. So be open with your doctor during the initial check-up.

  1. Eat healthy foods and stay hydrated: It is essential to follow a well-balanced diet that includes vegetables, fruits, nuts, dairy products, and grains. Also, make sure that you are drinking enough water.
  1. Limit caffeine and avoid junk food: Limit intake of coffee, fried and sugary food and stop consumption of alcohol and smoking altogether as that can adversely impact the pregnancy.
  1. Take prenatal vitamins: If you have been taking prenatal vitamins before pregnancy, you may continue them. However, consult the doctor as they may change the medications or the dosage if necessary.
  1. Take rest: As you tend to get tired quite easily now, take rest whenever possible. Also, don’t exhaust yourself by doing strenuous activities during this time of your pregnancy.
