When do you start getting symptoms after implantation?

So I'm honestly not positive if I'm pregnant or not. My last pregnancy I had no implantation bleeding that I was aware of. I was not tracking my ovulation so I wasn't sure how many DPO I started getting pregnancy symptoms (which I had sore boobs first. A week later nausea. I didn't have many symptoms.)

Anyways I THINK I may have had implantation bleeding. Honestly not positive because I don't track my ovulation. Yesterday I had a tiny drop of blood on my toilet paper. Like so small it was the size of the tip of a pencil. After that nothing. I even orgasmed last night because that usually jump starts my periods if I'm close to starting (I swear it works 😂) - and I had no more bleeding.

Anyways right before I had that dot of blood, like 30 minutes before I had this really quick cramp. Not bad at all. Very mild. I probably wouldn't have noticed it if I was standing up or walking around. It was in my pelvic region and kind of felt like a very mild period cramp that was isolated to just one spot.

Okay. So I have had no symptoms. My boobs aren't sore at all. Or not more than they usually are. No nausea. No fatigue. Nothing.

IF it was implantation bleeding, when would I start noticing symptoms?

Thanks!!
