std help ?? 😢

I had unprotected sex two days ago and my ex had told the guy I had unprotected sex with to go get checked because he said I gave him gonnorhea ' ( me and my ex had unprotected sex about three months ago ) I've been severely depressed and mad that I'm just finding this out and worried sick that it's been nearly three months and I never got tested for it .. my ex said he has symptoms but never been tested which doesn't make sense to me ' I've had a bartholin cyst that went away on its own and I feel I do have gonnorhea now although I have no symptoms .. I just don't want it to contract to hiv ' the guy I was with is getting tested also I just feel like shit if I would've known this I wouldn't have had unprotected sex with him I feel responsible and I feel horrible that I might have gave him something can please give me some insight I'm just worried sick hope this all makes sense ! ( im getting tested tomorrow )
