It just reminded me a little too much of Starr's stumble down a flight of stairs last year and then people finding out she was pregnant. While I wouldn't wish it on anyone, I do think she should lose the baby, go nuts (nuttier) and end up at St Anne's for a while.
But what I think will probably happen is that she will find out she's pregnant, try to lure Rex away from Gigi, again, in the end, motherhood, or at least the prospect of motherhood, changes her for the better. Don't really want to see that happen, because as much as I hate Stacey, she is a really good psychopath and OLTL hasn't had one in years. Plus, I read a while back somewhere that they plan on keeping Stacey around for a while and she will somehow be redeemed.
