Not if it is determined to be a very real health risk. Even my current wife- she had two sons and had been expecting a 3rd but going into her 2nd trimester- it was determined would at best be still borne and at worst, kill her. Hardest decision she ever had to make but she was able to raise her two boys into great young men.
On the other hand- abortion should not be a birth control. And in most cases, there is a term that had be determined when you could or could not get an abortion.
Life of the mother should be clear.
