think it more of a bug mainly because she acts like you have the belly when you don't because your still in the first stage plus I think I remember fawn saying you did this to yourself back when I did the same thing with her but I could be remember wrong
ya I know it just I thought fawn said her unique dialog before I got to late term I could be wrong because I did that a month or so ago
It also possible the bug is a result of how fast the others get to late term compared you and unique dialog if you have their child at the same time as they have yours
I just talked to fawn and she probably giving her unique when she just pregnant because before get to the point of being able to impregnate Alissa I had fawn child and she was say something on the line of "did I do this to you or more like you did this to your self" or something
And Alissa sounds more like both but could be wrong and that it default to you having there kid
