Help!

For the last couple days my discharge smells like urine, nothing is out of the ordinary. It doesn’t burn when I pee, my discharge is milky (2 dpo) I had a lot of sex while ovulating, I took a plan b pill two days ago but I didn’t take it within the 3 day window of having sex. Nothing seems different or weird, my period isn’t due for another 13 days. I constantly feel like I peed myself or like I’m about to start my period but I’ve never had this. What’s going on?
