HELP-5weeks pp and urgency to urinate and odor to urine?

Of course this is happening on the weekend. Much more comfortable going in to my dr office vs an urgent care center. Every time I pee, i feel the sensation to pee again. This just started. I can't comfortabley bounce or rock my baby- but could up until this sensation started 2 days ago. I think my pee has an odor to it. I'm going to have to pay attention- I've been using tucks pads for hemorrhoids so I'm not sure if I'm smelling witch hazel and/or my pee. No burning. I Drink lots of fluids. I don't know what's going on but it sure in uncomfortable!!! I'm still bleeding somewhat but obviously not with every pee! I'm breastfeeding- don't know if that matters. What is going on?
