What could be wrong if you've had pregnancy symptoms but your periods are regular and you had cramps so bad you could barely stand?

The only way to know for sure is by taking a pregnancy test. That may point to the possibility. Here's what to look for.

Do All Women Get Early Symptoms of Pregnancy? Every woman is different. So are her experiences of pregnancy.

Not every woman has the same symptoms or even the same symptoms from one pregnancy to the next. , those symptoms aren't always recognized. 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.

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. The bleeding and cramps, however, are slight.

Besides bleeding, a woman may notice a white, milky discharge from her vagina. That's related to the thickening of the vagina's walls, which starts almost immediately after conception.
