Definitely not a fetus. Two, "at least 40% of [natural] human pregnancies are lost before implantation" [2]. With assisted reproduction, that's 75% [3]. But "total loss from fertilisation to birth is 40-60%" in natural births [4]. About 65% to 80% of IVF implanted embryos result in a live birth [5], or about a total loss of 80%. (And improving.) When ART results in a lower total loss from fertilisation to birth than natural conception, would you argue for banning the latter?
