"How long, in weeks, does four months of pregnancy equate to?"
In medicine, 4 weeks are considered as one month. Therefore, 4 months refer to the period from the 16th week to the end of the 19th week. The average number of days for pregnancy is 280 days, or 40 weeks, which is what we call a ten-month pregnancy. Typically, both the calculation of pregnancy duration and the estimation of the expected date of delivery are based on the first day of the last menstrual period. The expected date of delivery is determined by adding 280 days (40 weeks) to this date. However, since it is generally difficult to determine the exact date of fertilization, the former method of calculation is more convenient. Nevertheless, these 280 days include the period before pregnancy, which is normal. In fact, the pregnancy duration or expected date of delivery calculated using this method is primarily for the convenience of various prenatal checks and there is no need to determine the exact time of fertilization and pregnancy.
Notes for the Fourth Month of Pregnancy
Reasonably adjust your diet. Pregnant women with allergies should adjust their diet starting from the fourth month of pregnancy and avoid foods that are likely to trigger allergies. Instead, they should consume fresh and protein-rich foods such as fish, milk, eggs, beans, meat, and cereals. Foods such as pears, watermelons, tomatoes, coconuts,哈密瓜 (substitute with a known English fruit like melon), cigarettes, various alcoholic beverages, chocolates, walnuts, dried fish, and processed foods should be avoided.
- Pregnant women with skin allergies should wear loose-fitting clothes and avoid tight belts to prevent skin compression.
- Avoid wearing woolen clothing and using blankets as they can irritate the skin, and the dust from wool fibers and carpets can trigger asthma attacks. Therefore, it is advisable to use cotton-based clothing.
- When experiencing skin itching, refrain from scratching as it can cause significant damage to the affected area, increasing the likelihood of future allergies and expanding the itching area, thus creating a vicious cycle.
