Before you even take a pregnancy test, you might notice some early signs of pregnancy. However, since many of these symptoms are similar to those you experience right before your period, it can be hard to tell the difference.

Breast changes:

Tender, swollen breasts and darkening, bumpy areolas are common early pregnancy symptoms. The areolas may also darken and expand in size.

Fatigue: 

Pregnancy requires a lot of energy to build the placenta, which can cause fatigue to set in soon after conception.

Implantation bleeding: 

Light spotting or bleeding, which occurs before your expected period, may sometimes be a sign of early pregnancy.

Changes in cervical mucus: 

If your cervical mucus becomes creamy and stays that way after ovulation, it could be a sign that your pregnancy test will come back positive.

Frequent urination: 

This is caused by the pregnancy hormone HCG, which increases blood flow to your kidneys, helping them eliminate waste more efficiently.
