Usually, when we talk about pregnancy, we mean that the egg excreted from a woman’s ovary and the male sperm combine to become a fertilized egg with the ability to develop, the woman stops menstruating, and the fertilized egg gradually develops, grows, becomes a mature fetus in the mother’s uterus, and is then born… The next thing you and your loved one need is to make up your mind to get pregnant and prepare for the pregnancy in every way! The first 4 weeks are very crucial and mothers must pay attention to them. The first day of the first week of pregnancy is equivalent to the first day of your last period. You are not pregnant at this time and you are still on your period, but you must be ready for conception afterwards. From now on make good lifestyle choices, stop smoking, stop drinking and stay away from drugs, and take a folic acid or multivitamin supplement containing at least 0.4-1 mg per day. In the reproductive cycle, the uterus prepares for conception every month. The first day of your period is the first day of your menstrual cycle and ovulation usually occurs 14 days before your next period. If your period does not come on time, you may be pregnant! Week 2 of pregnancy As you enter week 2, you will soon be ovulating according to your basal body temperature. Now you should be ready. Your dominant follicle is competing with other follicles to fully mature (on days 5-13 of your menstrual cycle) and break free, its estrogen production is slowly increasing, and the endometrium is thickening under the influence of estrogen and is in a proliferative phase. Everything is being prepared for ovulation and conception. So, together with your husband, relax, adjust your health and wait for your mission to be completed at the best time. From now on, you will have an added responsibility in your life, your husband and you will end your life together, your baby will be happy with you and your motherly nature will be at its fullest. 4 Weeks of Pregnancy If last week was your ovulation period and you had intercourse during it, without any surprises, this week, i.e. the 4th week of pregnancy, the fertilized egg is planted in your uterus, which means you are pregnant! First of all, the fertilized egg is planted into the endometrium and there may be a little bleeding. Secondly, if you are particularly sensitive, you may have some signs of early pregnancy reaction: weakness, anorexia, nausea, morning sickness, breast swelling, and changes in your skin and hair. If there is a sudden onset of severe pain in the abdomen with nausea, vomiting, or even fainting, or a small amount of vaginal bleeding, consider that it may be an ectopic pregnancy. Especially if the tubal pregnancy ruptures, internal bleeding can be critical, and in serious cases, massive blood loss and shock within a short period of time, or even death. Therefore, in such cases, one should not stop for a moment and take the patient to the hospital immediately for examination. A positive result can be obtained by a sensitive blood HCG test during this week, but if you test the urine pregnancy test (HCG) at home, it is likely to be negative. If the result is negative and you have some of the feelings you had before your period, you will need to retest the urine pregnancy test or go to the hospital to get a blood test to clarify the result. When you find out you are pregnant, you may feel incredulous and then start to remember what you have done in the past month, the environment you have been exposed to, and more or less everything that you feel is not quite perfect. Remember, excessive anxiety is bad for the baby. The doctors’ theory is “all or nothing”, which means that if you are exposed to an environment that is toxic to the embryo after fertilization and before the embryo is firmly implanted, the fertilized egg will not implant, or the embryo will abort early on, if the embryo is firmly implanted and developing normally. If the embryo is firmly implanted and developing normally, in most cases what you consider to be “unsafe” will have little effect on the embryo. What is the effect of working in a radioactive environment on pregnancy? Does radiation protection clothing work? A: All objects in nature, as long as the temperature is above the absolute temperature of zero degrees, are in the form of electromagnetic waves and particles constantly transmitting heat to the outside, this way of transmitting energy is called radiation. Common sources of electromagnetic radiation in our daily life such as radar systems, television, cell phones and radio transmission systems, radio frequency induction and dielectric heating equipment, radio frequency and microwave medical equipment, a variety of electrical processing equipment, communication transmitting stations, satellite earth communication stations, large power generation stations, power transmission equipment, high voltage and ultra-high voltage transmission lines, subway trains and electrical trains and most household appliances are able to produce a variety of Forms, different frequencies, different intensity of electromagnetic radiation sources. The so-called “working environment with radiation” must be clearly distinguished. If the radiation is generated by electronic products such as cell phones, computers, TVs, microwave ovens, hair dryers, etc., you should not be overly anxious. Although some researchers and environmentalists claim that long-term exposure to cell phones may have an effect on the head, and some studies have linked long-term cell phone use to the development of certain types of brain tumors, the evidence is not strong. Pregnant women have also been advised to stay away from cell phones, saying that they can affect fetal development as well as create behavioral problems in the future. Some studies have also reported a relationship between living near cell phone base stations and problems during pregnancy. However, there is no clear scientific evidence to date to confirm these above associations. Our advice is not to be exposed too often, for example, you can use headphones to answer the phone, do not talk for too long every day; do not stand next to the microwave oven when using it; do not sit for a long time to read the computer, watch TV, if this is your work needs, then sit in front of the computer for an hour to get up and move for 5-10 minutes. As for the commercially available radiation protection clothing in the end does not work, this is a matter of opinion, we can not give you the exact answer. But if your work environment may have radioactive materials processing, or in the hospital chest X-ray, CT, interventional and other frequent application of radiation department work, for you and your child’s health considerations, before pregnancy and pregnancy should be as far away as possible.
