About a week before or so I missed my period and took a test and I was pregnant.
I know this thread is old but it came up while I was researching about implantation pinch. I agree with Almyk. With my first son, I felt it and didn't know what it was. I felt it almost immediately (within hours of doing the baby dance). This time around (10 years later) I felt the exact same pinch again within hours. This time unmistakably I knew exactly what the pinch was. My second child is due in November. :)
