TMI- Urine question

So, I've started wearing pads within the last week because my discharge has gotten so bad (I'm 30+3). Well, I've noticed that my underwear, with the pad, smell like urine. I'm not peeing myself, or I would know. I call myself wiping well, but still get the smell. Is this normal, or am I crazy?
