I agree with all the above posters! You would be causing yourself harm...Medical advice is a necessity.
If you are trying to 'kill' your baby you NEED medical help AND then EMOTIONAL COUNCILLING Afterwards take it from someone who hhad an abortion. Biggest mistake of my life, but I had no choice, I would have died.
You need to seek medical help because if this goes wrong can make you infertile!
There is also adoption to consider if you're unable to look after the child!
If you mean you don't want to be pregnant... this is NOT something you can take into your own hands. If you try to do this yourself, or even have someone help you, YOU could die. This is very dangerous.
If abortion is truly what you choose to do, you need to have it performed by a trained physicial asap. Really, the sooner the better.
don't "try" to loose the baby & risk your own life in the process.
If you are asking what to expect if you have been told you are going to miscarry (i.e., how to handle it if it happens at home), talk to your doctor.
If you are referring to causing yourself to lose the baby, it is very dangerous to do this without seeking medical help. If you truly do not want to be pregnant I would highly recommend you see a physician immdiately.
