What are the symptoms of pregnancy during breastfeeding?

Don't think that you can't get pregnant during breastfeeding. Many people may get pregnant during breastfeeding due to early menstruation and ovulation. Therefore, contraceptive measures should be taken even during breastfeeding. The most common symptoms are cessation of menstruation, tingling and itching of breasts again, and feeling very weak. These symptoms have not appeared before, and are similar to those of your first pregnancy.

Initial symptoms

1. Menstruation stops. This is the most noticeable.

2. The breasts feel tingling, swelling and itching.

3. Early pregnancy reactions.

4. Fatigue and weakness. In the early stages of pregnancy, you may feel tired and sleepy.

5. Frequent urination.

6. Breast changes.

7. The amount of food you eat suddenly starts to increase.

Calculation of due date

Since it is difficult for every pregnant woman to accurately determine the time of conception, medical regulations stipulate that the expected date of delivery is calculated from the first day of the last menstrual period. The entire pregnancy period is 280 days, or 10 gestation months (each gestation month is 28 days, and the fetus grows in the mother's body for 40 weeks, or 280 days). Pregnant women gave birth between 38 and 42 weeks of gestation, all of which were full-term. Since the length of each woman's menstrual cycle is different, it is normal for the estimated due date to differ from the actual due date by 1-2 weeks. The main calculation methods are as follows:

Calculated based on last menstrual period

Add 9 or subtract 3 from the month of the last menstrual period to get the month of the expected delivery date; add 7 to the day of the last menstrual period to get the day of the expected delivery date. For example: Ms. Zhang’s last menstrual period was March 13, 2008, and her expected date of delivery is approximately December 20, 2008. Ms. Li's last menstrual period was on May 28, 2008, so her due date is approximately March 5, 2009. The due date can also be calculated backwards from the first day of her last menstrual period to the 280th day.

Calculate based on fetal movement date

If you can't remember the date of your last menstrual period, you can calculate it based on the date of fetal movement. Fetal movements usually begin between 16 and 22 weeks of pregnancy. The calculation method is: for primiparas, it is the day of fetal movement plus 20 weeks; for multiparas, it is the day of fetal movement plus 22 weeks. (General)

Calculated based on body temperature curve

The last day of the low temperature segment of the basal body temperature curve is regarded as the ovulation day, and the ovulation day is counted back 264-268 days, or 38 weeks.

Calculated based on B-ultrasound examination

When doctors perform B-ultrasound, they can measure the biparietal diameter of the fetal head, the crown-rump length and the femur length to estimate the gestational age and calculate the expected date of delivery (this method is mostly used by doctors for B-ultrasound diagnosis).

Calculate from the time of vomiting pregnancy

Morning sickness usually occurs at the 6th week of pregnancy, which is 42 days after the last menstrual period. The expected date of delivery is 280 days after the last menstrual period.
