Pelvic pain after sex

I used to get a UTI every time I had sex, I started using the bathroom after sex and it helped me avoid a few UTIs. I used to experience pelvic pain after sex, and then I got a UTI shortly after so I always thought the pain was due to the infection. But nowadays, I've been taking cranberry supplements, peeing after sex, the whole bit. And I haven't had UTIs but the pelvic pain for a few days after sex still continues. It's not horrible but it's still there. Should I be concerned? Also ever since I can remember, there has always been a little bit of pelvic pain every time I have sex. Is this normal?
