While you're not technically pregnant during your first two weeks of pregnancy, the third week is when conception occurs. Physicians count the first two weeks as part of your pregnancy, even though you haven't conceived yet. At the end of the second week, your uterus is preparing a rich cushion of blood for your baby, and your ovaries are getting ready to release a fertile egg - or more than one in the case of multiple births.

During conception, the sperm meets with the egg in the fallopian tubes, and the growth and development of your baby begins. The chromosomes of both mom and dad pass on information to the fertilized egg, and your baby's sex is determined as soon as conception occurs. When two eggs are released from your ovaries, and fertilized by two different sperm, you will have fraternal twins.

Fraternal twins may be a boy and a girl, or two babies of the same sex, however, they will not be identical. Identical twins occur when one egg splits after being fertilized by the sperm. These babies will have the same chromosomal makeup, and are always the same gender. Fraternal twins are more common than identical twins. In the case of triplets or quadruplets, any combination of genders is possible. For example, one egg could split into three, or one fertilized egg can split into identical twins while another fertilized egg remains intact. This would result in identical twins and one fraternal.

At the 14 day from the beginning of your last period, you may experience some spotting or bleeding as the blastocyst implants into your uterus after conception. However, the majority of women don't even notice when this is happening.

You're pregnancy will last for 40 weeks (280 days) and consists of three trimesters. Soon after conception, you may not notice any pregnancy symptoms for a few weeks or months. Every pregnancy is different some women don't experience morning sickness until their second trimester, while other women may feel it right away. Other women don't have morning sickness at all.

Hopefully, you've been taking your prenatal vitamins, including a folic acid supplement which will help decrease the chances that your baby will be born with a neural tube defect. If not, you need to talk to your doctor about taking a prenatal vitamin right away. In fact, as soon as you suspect you're pregnant, you need to make an appointment with your physician to confirm your pregnancy.
