How do I stop my pregnancy?

I personally wouldn't know, although I think your best bet would be having an abortion. I know you wouldn't want to do it but sometimes it's the best thing.
If you've been pregnant for a bit longer than that then I wouldn't be sure.

Well it's been 5 months? Did you "stop" it?

If you don't want the baby, give birth to it then give it up for adoption. I wouldn't have an abortion for 2 reason #1 it kills the baby and if they do it wrong you may not ever have a baby again and #2 is -after you do it you will regret it the rest of your life!!!

Fall down a flight of stairs, just kidding, seriously I know quite a bit of people that have gone through this, and personally there have been times that were close, but the safest thing to do is tell someone you trust who can take you to a clinic. It also depends on how far along you are, so go right away or else it may be too late for an easy solution, not that any decision is easy.

Abortion....nobody wants to do it...but sometimes you have to.

Depends on how far along you are. You need to see a doctor immediatly. I know it will be hard but I strongly suggest telling your parents or maybe an aunt or cousin. Someone you trust. However you decide to handle, this will stay with you for the rest of your life. If you can't make it to your reg. doctor, try looking for a teen pregnancy clinic in your area. In california it is called planned parenthood. Whatever you do make sure you are positive about your decision and you can live with the result.
