It's important to be well-informed about pregnancy - even if you think you are knowledgeable about it, check out the Internet resources in the list. Have a good read and browse through the links. Becoming pregnant is a huge milestone in anyone's life, and if it's not what you're planning, it is a sobering challenge to deal with. For some it's the first ever taste of a major life decision and unplanned pregnancy can happen to any woman who has sex.
If you find yourself unexpectedly pregnant, first of all don't panic. You need to keep a cool head so as to think your way through this carefully and make the right decision for you. This is a decision that you will live with for the rest of your life, one way or another, so you must be sure to choose the path that is right for you, for your own reasons, not someone else's.
If anyone puts you under pressure to make a choice one way or the other, they do not have your best interests at heart. A professional's job is to inform you, listen without judging, and help you to make your own decision, the one that is right for you. Any professional who tries to push you one way or the other is being very unprofessional. Any friend or family member who is pushing you one way or the other has their own agenda in mind, not yours.
People who make the wrong decision for themselves invariably have emotional or practical problems some time later. If you seek good quality advice and support, you really can make a decision that you can accept and live with happily.
