Do you have implantation bleeding for all pregnancy?

Not all pregnancies result in implantation bleeding. Implantation bleeding is not a reliable sign of pregnancy, and it is important to note that implantation bleeding does not occur in every pregnancy. In fact, it is estimated that only about 25-30% of pregnancies result in implantation bleeding. If you are concerned about whether you may be pregnant, it is best to take a pregnancy test or consult with your healthcare provider.
