implantation???

i know i sound insane but i swear on everything holy i’ve never felt this before. 7dpo after unprotected sex, not trying to get pregnant but a baby would be a blessing. on my right side near my belly button i felt a pinching, needle like sensation that lasted about 5 minutes. it almost felt icy. not super painful but definitely couldn’t be ignored. it’s coming in little twinges now but i SWEAR i have never felt anything like this before. could it be?

have you felt implantation? am i insane? i know im symptom spotting but i promise this feels different than anything ever.
