Implantation cramps?

Hi:) im trying to have a baby. We have tried on the third and fifth of this month and last night. About eight to nine days after we did i started to get cramps and on the left side of my lower abdomen right next to my pelvic bone i got a sharper pain. Its gone it was the worst then. Now its like off and on low rumbly pain.

Cooullld it be implantation? With my first born i had cranps and no period so i went to the doctors. Im just so excited and anxious. No bashing if you think its a stupid question. Im waiting for my period in five days. Andthe first two times we tried on the third and fifth i was ovulating:)
