STD help

So I recently got treated for Chlamydia and my partner and I both got treated and we waited a exactly a week to have sex like my OBGYN said last night we finally had sex and it was amazing but I was a little swollen afterwards and now I feel like some of my symptoms are back such as having to feel like you need to pee but you don’t? Have you guys experienced symptoms after treatment.. I plan to get retested in a couple a weeks but I just need to know did I possibly reinfect myself last night doing this..?
