Embarrassing issues

After my 2nd, I've had stronger body odor especially in my armpits and I've tried so many deodorants with no luck😫 I just started dating this guy that means alot to me and I'm so embarrassed he's smelling my BO which I try so hard to get rid of. I plan to do an armpit detox once I get some bentonite clay, but what can I use in the meantime?! Like what's the strongest deodorant out there?! I've tried secret, clinical strength, dove, all sorts of natural deodorants but nothing keeps me fresh past a couple hours. Another more embarrassing issue is I think I'm having pee leaking because lately I've been smelling straight up urine on my underwear & I'm mortified! I gave birth to both my babes vaginally & wondering if something got damaged during the process? Sounds stupid but I don't know what else to think. I'm only 32, I can't be having bladder control issues already! Anyone experience this postpartum? Any ideas? I'm 9 months PP btw.
