I'm not sure if it was the exact moment, but I'm pretty sure I could almost feel it growing, or maybe it was just in my head, I'm not 100%

I have to say that yes you can feel fertilization! Although many people swear that you cannot feel it.

When i was first pregnant, i felt a sudden prick / pinch on my right side ( i knew i had already ovulated) so i thought it might be conception.
A few days later I felt this sudden cramp on the lower right side of my V. which i assume was implantation (no spotting at all).
A few days later i got BFP!!!

I am now TTC again, and a few days after ovulation i got two pricks / pinches on my left side at different times during the day, different place of my left side.

(Almost as if someone got a needle and poked me inside) it made me jump.
And just a couple days ago i felt the same sudden cramp on my lower left side of my V. I'm praying and hoping that it is implantation.
And hopefully in a few days time i'll get a BFP!

Good luck to all!
