Too soon for symptoms?

Hey Guys! I’m 20 and we have been trying for baby #1! I believe I ovulated Monday and we had sex 4 days before and including Monday. I am now 4dpo and just experienced a (short lived) cramping to the right side of my lower abdomen. It came in waves and felt like a pulling sensation. And now my breasts feel ever so slightly sore. Could I have been feeling implantation cramps? Thanks for any thoughts and baby dust to everyone!! ♥️
