Yes.
Yes during periods of high anxiety
I've never actually leaked but I've had multiple times while not pregnant that in my dream I was peeing and woke up and felt like I was but I caught it in time but i did have to go immediately. I think after a baby our bladder is alot weaker. I mean if we sneeze or laugh to hard we pee( that def has happened to me). If it's happening multiple times a week I'd for sure contact your doctor. But if it's every once and a while and you don't have any pain when going or discoloration or smell etc than I think your ok
I had this not post partum but when I was much younger. I dreamed of swimming in a very shallow pool, tuned out I was lying in my urine. Haha!
