IVF, or in vitro fertilization, is the process of transferring embryos into the uterus. According to the American Pregnancy Association, this often happens when the embryos are at the two to eight cell stage. Immediately following IVF, a woman is asked to remain on her back for a few hours. After this, she may have to give herself hCG injections or use progesterone suppositories. Within 10 to 14 days, she may begin to notice the first signs of pregnancy.
Sore Breasts
According to the Mayo Clinic, a pregnant woman's breasts may begin to feel sore as early as two weeks after conception takes place. The way breasts feel in early pregnancy differs from woman to woman, but common descriptors are heavy, full, tingly or sore. It should be noted, however, that women using a progesterone suppository may also experience sore breasts even if they are not pregnant.
Fatigue
Severe, unrelenting fatigue is another common symptom of early pregnancy. The American Pregnancy Association reports that this symptom may begin as early as one week after conception takes place. This is because high amounts of progesterone cause sleepiness. Again, severe fatigue may also be a side effect of using a progesterone suppository.
Nausea
Nausea, commonly referred to as morning sickness, is another early sign of pregnancy that may occur soon after IVF embryo implantation. The American Pregnancy Association reports that most cases of morning sickness (which for some women may occur at different times, or even last all day) begin to appear between the second and eighth weeks of pregnancy. Nausea may or may not be accompanied by vomiting.
Heightened Sense of Smell
Many women experience a heightened sense of smell early on in their pregnancy. Some smells may suddenly become unpleasant (such as perfumes or certain foods), even if they did not previously cause this reaction. For some women, strong smells can even trigger nausea and vomiting. Like morning sickness, heightened smell can begin as early as two weeks after conception.
Food Cravings
The hormones of early pregnancy may cause some women to crave certain foods, or certain food combinations. Along these lines, some women may also find that certain foods trigger nausea. This is known as a food aversion. A newly pregnant woman may suddenly find her favorite meal makes her sick, which can be one of the first noticeable signs of pregnancy. She may also crave foods that were previously not favorites. According to the Mayo Clinic, food cravings and aversions may appear any time during the first trimester.
High Basal Body Temperature
An elevated basal body temperature, or BBT, can be another early sign of pregnancy. A woman's BBT goes up when she ovulates, and stays elevated until she begins her menstrual period. If it remains elevated for more than two weeks, she is most likely pregnant. Women who track their BBT may know they are pregnant before any of the other signs of early pregnancy begin.
