Another std? Greattttt could this be one

I know I’d have to go to my OB to get the real answer but I am very paranoid now when it comes to sex. I just got out of a 5 year relationship because I found out I had an std after having my ex’s son and that’s how I found out he cheated. Fast forward months later I found a guy and we had sex and I got another std... so now I’m over overly paranoid. Met this new guy and we teased eachother alittle went in alittle I knew I should of wore a condom either way. But it was in the moment and I’m just a dumbass I know that so please no negative comments. Now I’m paranoid I have an std. my body is still getting used to periods I finally got my first period last month after 10 months of having my son. I’m having sticky mucus and a smell not strong but a smell and I pee alittle more then usually but I have been drinking more and I just got put on a new medicine which I had to get off because of so many side effects. could that be everything adjusting since my period came back or did THIS guy give me an std. I’m scared to go to my OB because I’am always always there and I’m so embarrassed.
