C-section scar tickles?!

I had a c-section with my son 21 months ago. We are currently ttc our 2nd and have been trying for about 5 months. At about 4dpo the scar from my c-section started to tickle so bad! It felt like I was being tickled internally. Has anyone else experienced this?! I'm about 10dpo now and I've had this feeling off and on, and today the tickle feeling was also in my lower back. I don't like testing early so I'm waiting a few more days, but is this a good sign?! Has anyone else gone through this and had a bfp?!
