tmi pictures!! any feedback please :)

Im 13/14 dpo, i’ve been having nausea, back pain, tingling/burning nipples & cramps like period cramps. Me and my spouse just had intercourse, (we do foreplay before so i’m not dry or hurting). im suppose to get my period tomorrow. I’ve never had this before period especially this color. The spotting stopped (no blood or cramps) , didn’t get in my underwear or toilet. It lasted about 5-10 minutes after sex and now it’s gone. still no spotting or having cramps with AF being tomorrow.

Could this be implantation or causing it be affected or cervix being stretched???? I don’t have any itchiness or smells or anything like that so i know it’s not a infection.
