Possible Needlestick but unsure?

Hello everyone, I am a CNA who is working on getting my RN license. Recently, I was floated to the ED to help out. The charge nurse wanted me to help prep beds as they transfer/discharge patients throughout the day. After a young patient was transferred, I cleaned the bed and side table. The RN of that patient left many unused items such as IV start kits, unopened needles for IV start, syringe caps etc. I picked each item one by one and threw them all in the same trash.

Once I finished, i took off my gloves and noticed a red dot on my hand near the palm. I was sure that there was not any open needles on the side table but I couldn't help but think i was possibly stuck. I told my co-worker, also a CNA, and we dumped the trash can and rechecked. Again there were no needles. She said don't worry but I cant help but think what if I was pricked?

I did not notify charge nurse or anyone else because I didnt think i was pricked but I feel doubtful.

The red dot on my hand could have been from cleaning another patients bed, or could have been from anywhere else. I just didnt notice until at that moment. I didnt feel any pain or anything, but what if i was pricked? I mean, blood is supposed to leak when you get pricked but theres no blood leaking or scab formation...

It has been 3 days afterwards. The red dot is still there. its blanchable when i squeeze the skin around it. No scab. maybe I'm just nervous for no reason and it is really nothing.
