I went and got tested and the health department said something alarming to me?

Now i always thought its a good idea anyone who is sexually active, even if condoms are used from start to finish should get tested 1-2 times a year. So far this year i been using condoms each and every time.. I decided today to get a screen. Hiv came back ok, NGU as well. Others im still waiting on. However, before the tests, the nurse said based on me using condoms, i didnt have a risk and i didnt need to be tested. I know condoms work against most stds but isnt it still a good idea anyway to get check ups at least once a year?? They still tested me anyway but i was kinda alarmed though.. did i do the right thing by testing or did i waste reserouces?
