This is one of the WTS both sides of the mouth teachings: does life start in the womb or outside the womb. This comes under the topic of miscarriage. While the WTS says that a baby in the womb is alive, it is not eligible for a resurrection. This changed in 2009, suddenly resurrection for a child who died in the womb might be resurrected.

Would it be reasonable to think that if a “hidden miscarriage” had occurred in Job’s case, in the New Order that microscopic embryo would be restored to his mother’s womb to continue a pregnancy of which she might have been unaware? That does not conform to what the Bible shows about the resurrection, which always involved persons who had been born and existed as separate individuals before God.—John 5:28, 29; Acts 24:15.
But what if the embryo was more developed, had become a fetus or even was close to full term? There are many possible situations. However, there is no point in speculating, for there are countless sad consequences of imperfection suffered today. In the restored Paradise our loving heavenly Father will reverse man’s sinful condition and bring marvelous blessings. Many people will be resurrected. The decision as to how the resurrection will be carried out, and to what extent, rests with Jehovah and Jesus. We can be sure that the decision will reflect Jehovah’s perfect wisdom and justice.

To summarize, then, the Bible clearly teaches that life begins at conception and that Jehovah sees the unborn child as a unique and valued individual. In the light of those Scriptural truths, some might see it as inconsistent to argue that there is no hope for a resurrection of an unborn child that dies. Indeed, they might feel that such an argument undermines our Scriptural stand against abortion, which is largely based on those very truths.
In the past, this journal has raised some practical questions that seem to cast doubt on the possibility of a resurrection for children who died before birth. For example, would God implant even a partially developed embryo in the womb of a woman in Paradise? However, further study and prayerful meditation has led the Governing Body to conclude that such considerations do not really have a bearing on the resurrection hope. Jesus said: “All things are possible with God.” (Mark 10:27) Jesus’ own experience demonstrated the truth of that statement; his life was transferred from heaven to the womb of a young virgin—surely an utter impossibility from a human standpoint.
Does all of this mean, then, that the Bible teaches that children who perish before birth will be resurrected? We must emphasize that the Bible does not directly answer that question, so there is no basis for humans to be dogmatic on the matter. This subject may give rise to an almost endless variety of questions. Really, though, it seems best to avoid speculation. What we know is this: The matter rests with Jehovah God, who is abundant in loving-kindness and mercy. (Ps. 86:15) Unquestionably, it is his heartfelt desire to undo death by means of the resurrection. (Job 14:14, 15) We can be confident that he always does what is right. He will provide healing for the many wounds inflicted upon us by life in this wicked system of things as he lovingly directs his Son to “break up the works of the Devil.”—1 John 3:8.
