What Symptoms Do You Experience In The 5th Week Of Pregnancy?

Your pregnancy will be confirmed in this week, and there will be a surge in the hormonal levels. Here are the early pregnancy symptoms you might experience during this week:

  • Morning sickness
  • Lightheadedness due to the change in the blood pressure levels can cause lightheadedness
  • A heightened sense of smell may make you averse to certain smells
  • Fatigue because of the hormonal changes and the extra work the body does to nourish the baby
  • Food cravings and aversions
  • Constipation As the digestive process slows down
  • Vaginal discharge to prevent bacteria from reaching the uterus through the vaginal passage
  • Excessive saliva; in the case of morning sickness, your mouth gets exposed to acidic content, which is neutralized by the excess secretion of saliva
  • Frequent urination
  • Cramps due to the implantation of the egg
  • Light red or pink discharge, which could be the implantation bleeding
  • Swollen and sore breasts
    • Mood swings

When To Call Your Doctor?

Call your doctor if you notice the following symptoms (9):

      • Pelvic pain and mild cramping
      • Vaginal bleeding
      • Fever of 100.4 degrees or higher
      • Dark-colored urine
      • Less or painful frequent urination
      • Vomiting that lasts longer than 24 hours
      • Feeling like passing out or fainting

If you experience only the early signs of pregnancy, then schedule a regular appointment with the doctor.

How To Prepare For Your First Appointment?

This is the first time you will probably be meeting the doctor after your pregnancy has been confirmed. Here are some tips on how to prepare for the first appointment:

      • Carry all the medical records that specify any medications and supplements you are on.
      • Note down your LMP (last menstrual period) as it helps to calculate the estimated due date (EDD). If you have irregular periods, you may find it difficult to track the LMP.
      • In such a case, the doctor will do an early scan to determine the gestational age.
      • If tests or diagnostic procedures are recommended, find out why they are required. Moreover, if you have had any complications discuss that and also ask questions about any concerns you have.

Your OB/GYN Visit

During your visit, the doctor will check your weight and blood pressure.
The doctor may also recommend a flu shot (not a nasal mist) if you are pregnant during the flu season (10). Nevertheless, a flu shot can be given to pregnant women at any time during pregnancy.

The doctor may also ask you a few questions about:

      • The last menstrual period (LMP) date
      • Any history of miscarriage or abortions
      • Allergies
      • Allergy to any medicines
      • A family history of allergies
      • Any medications you are on

Pregnancy tests:

      • A blood test is done to determine the level of hCG hormone in the blood. At five weeks of pregnancy, the hCG level in your blood is between 200 and 7,000U/L (11) and the progesterone level is 12 to 20ng/ml (12). If there is any significant drop in the hCG or progesterone level, it may indicate an ectopic pregnancy. This test also checks for the glucose level, red blood cell count, HIV, Syphilis, Hepatitis B, and the presence of antibodies against chickenpox and German measles (13).
      • Pap smear test is advised if it is due in your case. This test is done to check for any infections like chlamydia and gonorrhea.
      • A urine test is done to check for the level of sugar, protein, and signs of infection.
      • The first ultrasound is usually done in the sixth week as the gestational sac becomes viable this week. However, if you experience cramping, bleeding, or have a history of ectopic pregnancy, an ultrasound may be carried out to check for any complications (14).

In the case of an ectopic pregnancy, the uterus will have a pseudo gestational, which is nothing but a build-up of fluids that mimics the true gestational sac (15). Also, an ultrasound will help determine twin pregnancy if two gestational sacs are visible.

Additional care at home is also necessary to avoid the risks at this stage.

Tips For The Mom-to-be

Here are some tips to follow:

      • Fix an appointment with the doctor.
      • Stay hydrated: drink plenty of water.
      • Eat foods that are a rich source of protein, vitamins, and minerals. Consume cereals, lean meat, fresh fruits and vegetables, and dairy products. Take prenatal vitamins like folic acid (400mcg/day) (16), which prevents neural birth defects such as spina bifida.
      • To relieve morning sickness, eat smaller meals at regular intervals.
      • Avoid smoking, drinking alcohol, and using illicit drugs.
      • Nibble crackles that are rich in carbohydrates.
      • Avoid excess caffeine.
      • Avoid deeply fried, fatty foods, salty and sugary foods.
      • Spend time with family and friends for emotional and mental support.
      • Wear supportive bras that can help relieve breast tenderness.

At this vulnerable phase, you could use your partner’s support as well.

Tips For The Dad-to-be

      • Accompany you to the first prenatal visit.
      • Create a pleasant environment at home.
      • Plan a day out to celebrate your happiness.
      • Discuss your plans for parenthood.
      • Help you around the house and keep worries at bay and make the journey of pregnancy a pleasant one.

The news of pregnancy can be an exciting one but comes with a bunch of questions and the anxiety of stepping into parenthood. There may be uncomfortable symptoms in the early stage of pregnancy, but they won’t stay for long. Keep that in mind and think about the joy you will experience with the addition of a family member. The journey won’t be that bad after all.
