Abortion when should it be allowed/stopped?

Once a fetus reaches a certain age its considered alive and shouldn't be abortiond. Before that is when abortions should be conducted. Cause its not considered alive or human or whatever. Religion is a huge factor in this. Most people who are against abortions are religion nuts. I hate religion. it runs out society. Im not gonna get into a religious debate here so no im not against abortion. And I think it will be continued.
