Hi girls! I used to moderate the Oct 2008 board before we converted to downsize. I just got a new BFP a couple weeks ago and I have had a LOT of people suggest that it could be twins because of how dark the line is. I thought I might ask some "experts" who have seen a BFP for twins before. This was two days before my period was supposed to start. I'll find out in about two weeks either way.
ETA: I have no history of twins in my family, nor does DH.
