However, at this stage, your doctor will say that you're four weeks pregnant. She'll count your pregnancy from the first day of your last period, because there's no way of knowing for sure the exact day that you conceived.

What follows is a description of some of the most common early symptoms of pregnancy. You should know that these symptoms may be caused by other things besides being pregnant. So the fact that you notice some of these symptoms does not necessarily mean you are pregnant. The only way to tell for sure is with a pregnancy test. Spotting and Cramping. A few days after conception, the fertilized egg attaches itself to wall of the uterus. This can cause one of the earliest signs of pregnancy -- spotting and, sometimes, cramping. That's called implantation bleeding. It occurs anywhere from six to 12 days after the egg is fertilized. The cramps resemble menstrual cramps, so some women mistake them and the bleeding for the start of their period.

Missing a period. There can be some symptoms of pregnancy after the day of conception but one can hardly rely on them for confirmation. Moreover, a sperm can survive inside the vagina up to 3 days if not more. So, you cannot rely on the night of having sex for any definite confirmations.
