Now in the US, it will up to lawmakers state by state to decide what if any limits to put on abortion procedures. Why it matters is suggested by the image above. The unborn has already his/her own heartbeat typically detectable by week six or seven, and by 12 weeks the rate reduces to a sustainable level for the rest of the pregnancy.
So the Supreme Court affirmed the Mississippi state law that prohibits abortion after 15 weeks. Women in Mississippi have the right to choose to end their pregnancy in the first trimester, but after 15 weeks the unborn has a right to life. There are many ways to practice birth control–abortion should be a last resort in extreme circumstances.
