I am 16 weeks & 2 days. At 16 weeks exactly, I was laying on my right side when I felt a tumbling motion on the left side of my stomach followed by flutters. It was simply amazing. I am a first time mom and never thought I would feel it this soon especially because I am a bigger women. I told my husband and he says it is too early (he has 2 kids already) but I know what I felt.
