Spotting after sex?? Delete if not allowed??

So I didn't knw were exactly to post this but here it goes.... Acouple days ago I posted something in ttc group were ive had my period 2 in 2 months.. And if it's happened to anyone and if anyone thought I could b pregnant?? Well long story short the second period was like 3 days very light bleeding finished on Sunday ... I haven't had sex with my partner since Friday of last week and we finally had sex yesterday night and after I went to pee and I didn't notice anything different or wrong... But this morning I woke up noticed pink spotting with a small discharge no red brown color just pink... Not spotting on my underwear or liner just wen I whip?? Just curious could I be pregnant or could this Just mean implantation...

Again sorry if this doesn't belong in this group I just didn't knw were to put it Cuz it has about sex ttc spotting and more lol... And Just in case I'm gonna put the t. M. I. On it lol jijijijij
