We had no idea. This is our 2nd pg but I showed early and grew out of my jeans at 6wks. I thought it was because my body was making a head start on growing the belly.

I almost bolted out the door when i found out we were having twins during our dating scan. I blamed DH but of course he had nothing to do with it.

Hope you find out soon. Congrats either way on the 3rd pg.
