Fetus
During the second week of gestation, implantation has not yet taken place and conception has probably not occurred yet.

Your Body
The menstrual cycle should be coming to an end which means the uterus is planning for egg implantation. Even if a woman does not plan on conceiving a child, her uterus will plan accordingly every month. The lining of the uterus will be lined with fresh blood vessels and tissues perfect for nestling baby and placenta. Ovaries are also preparing for conception. Eggs ripen in one of the two ovaries (in some cases, both ovaries). Once ripened, eggs are released into the fallopian tubes to move closer to sperm for conception. If conception does not occur, the egg will simply wash out of the body through the cervix. If conception does occur, the egg continues to travel until it reaches the uterus where it implants in the uterine lining for the next 30+ weeks of growth. If conception occurs, there may be a bit of bleeding and cramping associated with the egg implanting in the uterus, but many women never notice. However, it is a huge sign that baby is implanted and ready to grow.

Dad
Dad is still thinking about having a baby, conceiving a baby and what it means to be a father. At this time, there are few changes going on in his body or life. Sperm is being produced every day with millions of happy swimmers ready to meet the egg. It only takes one sperm to create a baby, but occasionally more than one sperm will reach the egg at the same time. If that occurs, Dad could be responsible for twins.

Tips:
—Keep following the pregnancy diet and prenatal vitamin regimen.

—Exercise is another huge benefit during pregnancy, so if you have not started an exercise program now is the time to start. Even after conception, exercise is allowed in most cases up until birth. Yoga and walking are perfect pregnancy exercises.
