Implantation occurs soon, at about 4 weeks pregnant. For implantation to happen, the cells in the fertilized egg, now a morula, will continue to divide until it becomes a blastocyst. About five to eight days after fertilization, the blastocyst will have arrived, where it will begin to implant in the wall of the uterus. What a journey! A pregnancy test might not be able to detect a pregnancy just yet.
Once you start testing, if you get a negative result, feel free to keep testing every couple days until you get your period. Your first morning pee is the most concentrated, making it the most likely to have a high enough concentration of hCG for the test to detect. Follow the directions exactly for the most accurate results.
Continue taking care of yourself You should still be taking your prenatal vitamins everyday, drinking plenty of water and eating healthy, balanced meals. Continue to get regular moderate exercise and practice self-care. Dairy products, leafy green vegetables, red meats, and legumes are great sources of folic acid , calcium, protein, and iron, all of which help develop strong bones, muscles, and tissues in the baby.
Plus, a healthy diet can help you to manage the mood swings brought on by the hormonal changes. During the third week the baby is called a morula. A morula is a ball of cells that is constantly multiplying. About 30 hours after fertilization occurs, the morula begins to divide into two cells, then four, then eight and so on, as it moves from the fallopian tubes to the uterus.
As the morula travels, it becomes known as a blastocyst, and it hollows out and fills with fluid. By the end of the week implantation occurs, meaning the blastocyst attaches to the lining of the uterus, or the endometrium. Once it has attached, the endometrium provides nutrients and removes waste from the embryo.
These tests can confirm a pregnancy by checking for a pregnancy hormone called hCG in urine. Keep in mind, if you take the test too early there may not be enough of the hormone in your urine yet for the test to be accurate. Check the packaging on the test you buy for information on when to take the test.
Some require you to wait until at least the first day of your missed period. Others can detect lower levels of hCG, and may be accurate a little earlier on.
If you think you may be pregnant but the test says otherwise, try again after a few more days or speak to your healthcare provider.
You can also ask your healthcare provider to confirm your pregnancy. Your provider will do a blood test. Think you might be pregnant? Take our Am I Pregnant quiz. Keep in mind, only about 5 percent of babies are born exactly on their due date. Your healthcare provider can also give you an estimate of when your little one will be born. Due dates are typically calculated as days, or 40 weeks, from the first day of your last menstrual period. See all in Preschooler. See all in Life as a Parent.
