In many cases, pregnancy can occur in as little as 10 days post ovulation. In these cases, it is difficult to distinguish the symptoms of early pregnancy from those of upcoming menstruation. Symptoms such as spotting, cramping, breast tenderness, bloating and nausea are all common side effects of fluctuating hormone levels. These symptoms may be felt due to normal cycling of hormones or because implantation of a fertilized egg has occurred.
Also called implantation bleeding, spotting may occur at 10 days post ovulation. This is a result of the egg implanting in the uterine lining, and is brownish or pinkish in color.
Another side effect of the egg implanting is cramping. Some women feel pain when the egg implants, though this is often indistinguishable from normal premenstrual cramps.
Delayed or Absent Menstruation
The release of hormones related to pregnancy stop the body from shedding the uterine lining as normal. This results in a delayed or absent menstrual period.
The changing levels of hormones can also contribute to swollen, sore, tender breasts. This symptom is common in early pregnancy and is often one of the first signs to appear.
Morning sickness is commonly associated with pregnancy, and dizziness and nausea may be felt shortly after conception. The result of changing hormone levels, this morning sickness passes in most pregnancies.
