What Are The Symptoms Of PID?

I ve recently been treated for Chlamydia. All of my symptoms have disapeared. I feel great. I have had problems getting pregnant the last few years or so. I never thought that having an STI would be the reason causing that. Since I recently got treated, and not sooner, do you think I have PID? When I got treated for Chlamydia, they took a urine sample, and a blood sample. If I had PID, wouldn t they have told me?
