Pregnancy??


Hello Dr.
Zhao: I got my period on December 14, but it didn't come as expected on January 13.
I took a pregnancy test, and it was positive.
How is the pregnancy cycle calculated? How many months or weeks and days am I now? What should I pay attention to? Is it safe to be intimate with my husband during pregnancy? Will it have any impact?

Dr. Zhao Chengxiang reply Obstetrics and Gynecology


The gestational age is calculated starting from the first day of the last menstrual period, with a total of 40 weeks leading to the due date.
A simple method to estimate the due date is to subtract 3 months from the month and add 7 days.
Your due date is September 21, and your current gestational age is 4 weeks and 2 days.
For patients with irregular menstrual cycles, the gestational age must be confirmed using ultrasound.
Therefore, if your menstrual cycle is irregular or exceeds 35 days, it is recommended to visit a clinic for examination.
What should you pay attention to? Avoid taking medications without consulting a doctor and ensure you get plenty of rest.
Is it okay to be intimate with your partner during pregnancy? Yes, it is safe and will not affect the pregnancy.

Understanding pregnancy can indeed be confusing, especially when it comes to calculating gestational weeks and understanding what to expect during this time. Based on your last menstrual period (LMP) of December 14, and the fact that your cycle is typically 28 days, you can estimate your pregnancy weeks as follows:
1. Calculating Gestational Age: Pregnancy is typically calculated from the first day of your last menstrual period. In your case, if your last period started on December 14, and you missed your next period on January 13, you would be considered approximately 6 weeks pregnant as of today (assuming today is February 1). This is because pregnancy is counted as 40 weeks from the first day of your last menstrual period, and you would add two weeks to the actual conception date, which usually occurs about two weeks after your LMP.

2. Current Week Calculation: To break it down further, if today is February 1, and you calculate from December 14, you would count the weeks as follows:
- December 14 to December 21: 1 week
- December 21 to December 28: 2 weeks
- December 28 to January 4: 3 weeks
- January 4 to January 11: 4 weeks
- January 11 to January 18: 5 weeks
- January 18 to January 25: 6 weeks
- January 25 to February 1: 6 weeks and a few days.

So, you are approximately 6 weeks and a few days pregnant.

3. What to Watch For: During the early stages of pregnancy, it’s essential to maintain a healthy lifestyle. Here are some tips:
- Prenatal Care: Schedule your first prenatal appointment as soon as possible. This is crucial for monitoring the health of both you and your baby.

- Nutrition: Focus on a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Folic acid is particularly important in the early stages of pregnancy to help prevent neural tube defects.

- Hydration: Drink plenty of water to stay hydrated.

- Avoid Harmful Substances: Stay away from alcohol, tobacco, and recreational drugs. Limit caffeine intake and avoid certain foods that may pose risks, such as raw fish and unpasteurized dairy products.

4. Sexual Activity During Pregnancy: It is generally safe to have sexual intercourse during pregnancy unless your healthcare provider advises against it due to specific medical concerns. Many couples continue to have a healthy sexual relationship throughout pregnancy. However, if you experience any bleeding, cramping, or other unusual symptoms, it’s essential to consult your doctor.

5. Travel Considerations: If you are considering traveling, especially if it involves long distances, it’s advisable to discuss this with your healthcare provider. While many women travel safely during pregnancy, certain precautions should be taken, particularly in the first trimester when the risk of miscarriage is higher.
6. Emotional and Relationship Considerations: Pregnancy can bring about a range of emotions and changes in your relationship. Open communication with your partner is vital. Discuss any concerns or feelings you may have, and support each other through this transition.

In summary, you are approximately 6 weeks pregnant, and it’s important to prioritize your health and well-being during this time. Regular prenatal care, a healthy lifestyle, and open communication with your partner will help ensure a positive pregnancy experience. If you have any specific concerns or symptoms, don’t hesitate to reach out to your healthcare provider for personalized advice.
