What do I do if I'm pregnant?

Hello,
I'm 19 years old and I've missed my period recently. I decided, maybe because of work and life, I'm just stressed and it's causing a bit of a stress delay, but I've also been finding signs of pregnancy. I know that period and pregnancy signs can be very similar, but I have a regular period and I know my body well enough to say something is not right.
But then here's what's been bothering me. Assuming I might be pregnant, I want to think ahead rationally and be sure of my actions.
I don't think I'm ready enough to support a child, but I'm very against abortion. Erasing a life that could be or even just the whole idea terrifies me. But I also think that I shouldn't raise a child so that one day he'd find out he was a mistake and happened by accident.
Does anyone have any thoughtful advice or words of comfort? It might help me feel a bit better in the meantime =)

Take a test to find out for sure... babies are hard work and if you are pregnant you need to keep it! do not kill it... now your just going to have to deal with the consequences umm maybe get on birth control if you are not thinking about having kids?? thats if you are not pregnant.

If anything consider putting it up for adoption with a good family if you dont think you can do it dont abort it thats the worst thing...But im sure if you pray to gof things will work out for you!!!

adoption is a wonderful option huni!Its so great that you dont want to get an abortion...and you realize that you may notbe able to give this child the best option possible...My mother ,father,aunt,and best friend are all adopted and now have relationshps with their biological mothers and are very thankful to their bio's for giving them the best chance at life...good luck!!!
