Typically, the first person you should tell will be the father of the child

The way you go about this will vary depending on your relationship. If you are in a serious relationship, you may have suspected pregnancy and taken the test together, in which case you both found out at the same time. If you are not in a serious relationship, chances are that you took the test alone, or perhaps with a close girlfriend. Either way, you will need to tell the father as he needs to be given the amount of responsibility that he is due. However, always keep in mind that while it takes two to tango, creating a baby does not a father make. You will initially have a 50/50 chance of the father being there for this child, so don't push him away by being demanding of him or you may lessen your chances. At any rate, the two of you need to decide what you are going to do, although it is ultimately your body and your decision.
