Drink a lot of alcohol and lemon juice
If you google around you can find all kinds of answers to that question. Most people will tell you to call Planned Parenthood or something, but that may not be for you. Maybe your Mom works there or for some other reason you can't go there. Maybe you just don't have any money, but what you can have is smarts! Do a little research into how Doctors kill the babies they abort. They use thing like super high doses of salt to dry the baby up. Some things like using a coat hangar or knife could be dangerous to you, not just the baby, and you don't want to cut yourself while you're cutting up the baby, and it might squirm and try to get away so this would not be a good idea. High doses of almost anything that causes chemical reactions in the body should be able to kill the baby though, just like chemo. Chemo in cancer patients targets cancer because cancer is more metabolically active than regular cells. In the same way a baby is more metabolically active than an adult so more of the "nutrients", which in this case will be poisons, will go to your baby and thus cause more damage to the baby than to you. Do some research. I bet you could surprise yourself and come up with a novel baby-killing method of your own if you just apply yourself.
Listen to the sentence you just said. You want to kill something that was your accident and has no control over weather it can live or not, a baby... But seriously, try and go through with the pregnancy there are so many people out there that want a baby more than you want it dead.
You can abort baby if your country's law permit. You can use medicines to induce abortion if the duration of pregnancy is less than 49 days. For more details, visit Medical abortion.
I don't think there are any type of "herbal" medicine to abort a baby. I don't condone to abortion but cannot tolerate irresponsible parents too... Just go into you local clinic and they are sure to help with a low cost or no cost issue. Usually there are programs that qualify anyone to receive free medical help from government funding. It's embarrassing but it's probably better for you.
You clearly don't know enough about life to even be pregnant >:/why risk gettin pregnant if you don't want the baby??? I'm not havin a go but think of all the people hu try for years for babies and get nowhere then you get people hu get pregnant then ask about something herbal to kill off their baby? :@
Its hard to believe that you actually want to kill your unborn baby that could probably help or even save the world in the future. Did your mother give up when you were still in her womb? You shouldn't either because children are the future and present.
