Co-parent
During the first, second and third week of pregnancy, you probably do not know that you are expecting a baby.
But perhaps early pregnancy symptoms are beginning to show; metallic taste in the mouth, nausea - Congratulations, your partner has been fertilised!
If you have had IVF, it is now that the embryo (a fertilised egg) has been inserted and you have a small head start and already know that fertilisation has taken place.
