Upon meeting the egg, the sperm must penetrate its tough outer membrane. Only a single sperm will be allowed in. A new organism is created when the nuclei of the sperm and egg are combined. The very first stage of pregnancy is now complete, but the longest part – the development of a combined cell into a baby – lies ahead. At first, you won’t be aware of the changes in your body, although the new life just created can make some women nauseous and cause breast tenderness.
Now would be a good time to check what medical care is offered during pregnancy in your country. Each country has its own system. There may be free or virtually free health care programs available to you.
