When is the due date of the last menstruation on May 3rd, 2020?

The specific calculation method for calculating the expected date of delivery from the last menstruation is as follows. If calculated according to the Gregorian calendar, it is the expected date of delivery calculated by adding nine to the month of the last menstruation and seven to the number of days. If calculated according to the lunar calendar, the month of the last menstruation plus nine and the number of days plus fifteen is the expected date of delivery of the lunar calendar. Therefore, to calculate the expected date of delivery, we must know the time of menstruation according to the specific time of the last menstruation, so as to correctly judge, but some women's menstruation is not very accurate, and the expected date of delivery can be calculated by the gestational age displayed by the first B-ultrasound, which is also very accurate.

Matters needing attention of delivery symptoms in late pregnancy

1. Pseudo-contractions: Quasi-pseudo-contractions begin to appear frequently in the third trimester, showing irregular time, sometimes strong and sometimes weak, and often occur within 2-3 weeks before delivery. If uterine contraction is accompanied by intense abdominal pain, such as fidgeting, work and life are affected, you need to go to the hospital.

2, seeing red: generally, seeing red appears 24 hours before labor pains, but it also appears repeatedly a few days before delivery or even 1 week. If it's only faint bloodshot, and the amount is not much, expectant mothers can stay at home and observe. Usually, they should be careful not to overwork and avoid strenuous exercise. If bleeding occurs, exceeds the amount of bleeding during physiological period, or is accompanied by abdominal pain, you should be admitted to the hospital immediately.

3, breaking water: fetal membrane is the container envelope of amniotic fluid, once there is breaking water, amniotic fluid will flow out. If it bursts suddenly and the breach is large, the expectant mother will feel that there is a sudden outflow of liquid from the vagina, and then continue, standing and pushing down (such as coughing) will flow more. If the break is small, it may be that a small stream of liquid often flows out and the underwear is soaked. If the pregnant membrane is ruptured, you should lie flat immediately and be rushed to the hospital for treatment.
