This is a bit gross but does anyone have increased body odour after having a baby?

I’ve never had a problem in my life and I hardly sweat, I could take a shower and go 2 days without reapplying deodorant or showering again and I’d be fine. But ever since I gave birth I’ll layer on the deodorant and after a five minute walk I stink 😭 it’s so disgusting does anyone else have this? And will it go back to normal???
