25 should were it is begun monthly, but they till now are not present. Tell or say for what reasons usually there are delays??? Can be iz-for colds, nerves??

Pregnancy, dysfunction of ovaries, reaction to stress, to disease.

For what day of a delay it is possible to do or make the test for pregnancy?
