After just three weeks of pregnancy, a woman may not yet know. There will be no major external changes to her body, although some pregnancy symptoms may have started.
The timeline of a pregnancy begins on the first day of a woman’s last menstrual period. Home pregnancy tests are designed to be used a week after a woman has missed her period. So she should wait until then to avoid fear of a false negative test and not to waste money.
At this stage of pregnancy the basal body temperature – Your body temperature when you are completely at rest – will be high. You may notice slight spasms, usually from one side. This pain is referred to as middle pain – German for “medium pain” – associated ovulation, when the ovary releases an egg. Some women experience an increase in vaginal discharge or mock, caused by the burrowing of the egg into the uterine lining. The lack of spotting is nothing to worry about as most women do not experience spotting in the first few weeks of pregnancy.
Other symptoms of pregnancy at this point include tiredness and exhaustion. Also, higher hormone levels direct more blood flow to the breasts, causing them to become tender and sore. The rapidly increasing estrogen levels can even lead to an increased sense of smell. Even though morning sickness usually starts after a few weeks, some women may experience nausea or vomiting at this stage. You may start craving certain foods, while foods you previously enjoyed begin to taste different.
development of the fetus
During the 1st and 2nd week of pregnancy, the fertilized egg moves into the uterus and becomes a blastocyst, or blastocyst – a very small group of cells the size of a pinhead. The part that evolves into placenta starts producing human chorionic gonadotropin (hCG), a pregnancy hormone. The hCG alerts your ovaries to stop releasing eggs and increases the production of estrogen and progesterone. There are amazing benefits of progesterone in a woman’s body.
As a result, your uterus stops shedding its lining and the placenta begins to grow. this is that hormone that pregnancy tests are looking for so that you may be able to take such a test at this time and get proof that you are pregnant. However, since this stage is different for every woman, you may have to wait a few more days for the test to detect hCG.
The area that becomes the amniotic sac begins to fill with amniotic fluid, keeping the fetus cushioned and secure. The blastocyst receives all of its vital nutrients through blood vessels, with the placenta eventually taking over this task. At this point, basic development continues, with the brain, spinal cord, heart, and gastrointestinal tract beginning to form.
diet and exercise
At this point and throughout pregnancy, you should avoid alcohol, caffeine, recreational drugs, and smoking. The fetus absorbs everything you do, and you don’t want to stunt fetal development. You should also avoid certain medications and foods; Check with your doctor to make sure none of your medications are harmful to the fetus.
This is when you should start developing good eating habits. To help the fetus grow, What to expect, a pregnancy advice website, suggests consuming three servings of lean protein daily. This will help with tissue development. A serving is about 85 grams, or the size of a deck of playing cards. This can be lean beef, chicken, legumes, or tofu. Lean red meat also helps with your iron absorption, which you need to support increased blood volume. Add some foods rich in vitamin Chow oranges and berries to aid in iron absorption.
Folic acid is also very important at this stage, as is calcium. leafy greens like spinach provide these two nutrients that help with bone development and prevent birth defects. Citrus fruits are naturally high in folic acid, so a calcium-fortified orange juice is a great addition to any breakfast. Talk to your doctor about adding a prenatal vitamin to your diet.
the American Pregnancy Association recommends checking with your doctor before beginning or continuing an exercise program, but exercise is very important at this stage. Focus on cardiovascular health to keep your heart healthy and strength training to reduce the potential for back pain throughout pregnancy.
