Is it the woman's right?

According to the Roe decision, most laws against abortion in the United States violated a constitutional right to privacy under the Due Process Clause of the Fourteenth Amendment. There are a lot of people out there who think that if abortion were illegal it would be violating women's rights. But is it a woman's right to end a life? Yes, it is her right to decide what can be done to her own body but is the life inside of her considered to be HER body? I don't think that women should have the right to terminate their pregnancy. Twenty one days after conception the fetus has a heartbeat. So in my opinion it would be wrong to allow a mother to stop the beating heart of her own child.
