Is this herpes? Or is this something else?

i slept with someone who was my ex, two nights ago and i never experienced this in my life. I have pain when I urinate and its very uncomfortable. feels like cuts inside of me. and i seen these forums where they post pictures similar to what mine look like and then they never respond to confirm what they had. I'm just so scared and cant stop crying. Can anyone help or does this look similar to anything? there is no smell but there is discharge.

the picture is pretty blurry its hard to see. Looks like it could be just irritated keep an eye and see if it blisters or maybe just get looked at. But from the little I can see looked like it’s just irritated
