Do you think they have birth control on the island? If I were Juliet and seeing women die all the time after becoming pregnant, I would not let Goodwin near me for fear I would have the same fate. I know that last season one of the Others consoled Juliet after one of the deaths saying, "it was her choice to get pregnant". I also remember Juliet saying something about sperm being like super sperm on the island. So, they got to have something!
