I think that if your personal morals say to keep the baby, then by all means do as long as you are sure you will have a way to support the child. If you feel as if abortion or adoption aren't the way to go, then don't make a decision that you know you will end up regretting. You can weigh the pros and cons of each option, but it seems as if you definitely are sure of yourself.

I know that my sister first had to visit Planned Parenthood because she didn't have any medical insurance at that point, and they confirmed her pregnancy with another test. From what I have just researched online, at the actual appointment, I'm assuming that what they will try to do is take your medical history and ask you if your family has any history of certain diseases, and maybe assess your current health or ask you if you do things like smoke or drink which can affect the baby. They may want to get a bit of information on your family life or may ask you questions about your boyfriend if you know the answers. They may assess your current health as well through things like a physical or blood test. If you have any questions at all at this time, definitely ask them! You may even want to bring up the topic of school and they may be able to give you some advice on that, or go over the options you have with your doctor.

As far as your boyfriend, he may need some time to process things before coming around, but I'm not saying there is a 100% chance of him doing so. It may hit him later on that you are giving birth to this child, but it's not a guarantee.

With your parents you probably should tell them sooner than later before you start showing any signs or symptoms, or before they find out through some other source. When you tell them, it probably would be best to sit them down on a day when they are in a relatively good mood in a calm area. Then, be honest with them. Let them know that you know that this is something serious and worrying, but you have been having sex with your boyfriend and recently discovered that you were pregnant. In other words, be as honest as possible with them and try and stay as calm as possible. If you don't think you can tell them in person you can always try writing them a letter.

If they kick you out, you can always try and find another friend or relative to stay with or see if there is a shelter in the area that will take you in.

No matter what happens, I know that in the end you will make the decision that is best for you.
