STI/ STD testing

Hi girls, I have a question.. I’m currently single, I’m 24 and just got out of a abusive relationship.. and I’m living.. (If you know what I mean) I’m having a phase where I don’t care about any relationship rn because of my past relationship so I’m just messing around and focusing on work. I’m pretty strict on myself, I always use condoms. Always. Never perform oral, now.. how often would you get tested. I would go “too” often. After every partner because I know I’m not 100% protected, the lady at the clinic told me to stop going so often because certain things don’t pop up until months later, she said every 4-6 months is ideal.

If you’ve ever had a “phase” how often would you go? Thank you

Edit- I have no symptoms but I’m going to be honest in one month I had three different partners, all with condoms. So I would go a lot just to be safe but she just told me recently when I went to not go in so often
