Soreness postpartum

Is it normal for soreness & pain to come and go postpartum? I'm 4 weeks pp and around 2 weeks my bleeding slowed down to brown spotting and my pain virtually went away. Now all of a sudden my pain is spiking. Its painful to pee and just painful in general. It doesn't feel like a uti/yeast/bv infection and nothing has been inserted into my vagina. I had a couple stitches, and honestly haven't been able to tell if there fallen out or not but I think they have. Wondering if I should call my dr or if this is to be expected 🤔
