Okay, I find this really weird and I don't know if it's just in my head or not. I only got my BFP 2 days ago and I'm like 4 weeks along. The day I tested I was wearing jeans that seemed to fit well, however, I did notice that I had pooch in my stomach that day. I thought I was just having a fat day. I could swear my belly has been slightly bigger each day since. Is this happening to anyone else?
