I agree with Jera. Trying to cause a miscarriage yourself can lead to further internal injury, not to mention infection, that's even if you were successful. Chances of causing yourself to miscarry in those ways are not likely. I read your other post where you stated you are late. Just take a test and if this is not what you are ready for then talk with a counsellor to consider other options. Also, remember you are not the only one responsible for the pregnancy (if there is one). Your partner will have obligations as well, whether you choose to keep the baby or not. Take care!!
