I didn't find out I was pregnant until I was 9 weeks; I started feeling symptoms around 8 & 1/2 weeks which made me then test a couple days later. As soon as I tested, it was positive, all 3 times. LOL.
My fiance was talking about doing that too, it's not strang at all, some weddings do it and some don't. The wedding is berve wrecking for the groom too, not just the bride, and I think a lot of people overlook that. Let him do it.
