I'm wondering if there was an obvious sign that you were having more than one baby?

I got my positive HPT at 7DPO. Morning sickness started at 3.5weeks, REALLY irritable and emotional. And im HUGE!! i showed early with DD but my goodness im massive!

There aren't twins in the family (or that i know of on my side) but the metformin i took for my pcos can cause multiples..
