If you perform an abortion on yourself without doctor's supervision that is an illegal abortion and yes, you can go to jail.
Nothing. It is both illegal and highly dangerous to attempt to give yourself a miscarriage. Anything you do use is more likely to make you very ill before it aborts the baby.
You could always have someone beat you up! I find this question to be creepy and queer. Labor really isn't as bad as it sounds, and there is no way to give yourself a miscarriage without injuring yourself badly as well. Although, after reading this question, I kind of feel like you would deserve it. Anyways, the safest way to get rid of the unborn fetus is to get an abortion at a clinic. Just for your information, however, an abortion hurts just as bad as labor OR trying to give yourself a miscarriage. :) Enjoy!
At 40 weeks it's not called a miscarriage but stillborn. You will have to give birth as if the baby was alive. They will induce the labor.
For a induced miscarriage aka abortion you have to see a doctor and he will give you a surgical or medical abortion depending on your health and how far along you are.
You always have to go see the doctor after a real or potential miscarriage. They will give you a D&C if not everything have passed.
I'm not aware of any tests that suggests this. Obviously, you can always miscarriage, but the chances of this will likely not be increased by him smoking marijuana. I would strongly advice you to not expose yourself to secondhand smoking (or smoke yourself for that matter) as that can have very negative implications for your baby.
Although I am not sure if you mean intentional or unintentional miscarriage, I know that there is a pill that is an "abortion pill" that does, indeed, cause a miscarriage.
There is no established period. You go right away and check yourself. No fear.
Yoga doesn't cause miscarriages, however if you are pregnant, practicing yoga and worry it might cause you a miscarriage, my advice is always: DON'T PRACTICE. While it may be illogical that you think that, if you do think yoga increases your risk, then if you have a miscarriage you may blame yourself and your practice.
Often one may go into epileptic shock and have a seizure. During this seizure, it's possible to fall, or in other ways hurt yourself. This type of miscarriage, however, is purely physical. Other than direct trauma to the womb, epilepsy should never cause miscarriage.
As long as the bleeding is settling there is no specific physical care needed after a miscarriage though you may feel emotionally fragile for quite a while as you have suffered a bereavement after all. Take care of yourself.
