What were your implantation symptoms?

Hi all/ I know it’s probably way too early to tell, But I am 5dpo and the last two days I’ve been feeling deep almost like someone is pressing on my lower abdomen with their thumb (lol trying my best to get a visual) but it lasts a few seconds. I’ve also had some fluttering on my lower right side and in the middle. Before I get too excited, just wondering if anyone experienced / is experiencing this as implantation?? and if you ended up w your bfp?? This is our third cycle trying and our first with preseed. Feeling really optimistic this time around so I’m jw !! Thanks girls!
