PLEASE HELP!!!! DID I CATCH SOMETHING?!?!? WHAT IS IT

I have been having sex with this guy for a little over 2-3 months now we use condoms everytime only once that ik of has the condom popped and I got a plan b that day. An ex of this guy who at the time did not like me at all went on a rant to me saying he has stds and he gave his previous previous girlfriend Chlamydia and she can’t have kids now. Since I’ve been having sex with this guy my vagina looks like this I looked up the signs of having Chlamydia and so far I feel like I’ve exhibited a couple. Other than around my vagina looking this way I spotted for my first time for a good week after my period and this weird discharge has been coming out please lmk what you believe it to be, what I should do next and what steps do I take to get rid of whatever I have if I do have it. Also what do I say to this man that may or may not have giving me this std how do I approach that conversation and should I even keep the relationship going? PICTURES ARE VERY GRAPHIC. HAD TO SHOW IN ORDER TO GIVE A CLEAR DESCRIPTION AS TO WHAT IM SPEAKING ABOUT.‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️
