#TTC (age 20) Ladies help!

Have you actually been able to pinpoint when implantation took place? Just curious because today is cycle day 17 and I just got a sharp, persistent achy feeling in my right ovary and kinda my belly button for about 10 minutes and then it went away. I wasn't sure if implantation cramping is something you can actually remember taking place. Please let me know if you've experienced it first hand and gotten a BFP! :)
