This might be tmi but I thought I was leaking urine changing my underwear 3 + times a day. One day I told my girlfriend she suggested I go to my ob and it was discharge watery, slightly color no strong order, weirdest thing ever. Dr. Said wear a mini pad
Yes do kegels. For the leakage, start wearing panty liners. It will save you on doing so much laundry.
I strongly suggest you do your kegel exercises if you aren't already. Pregnancy can put a lot of strain on pevlic floor muscles and if the muscles aren't strong it can lead to incontinence. Definitely mention it to your doctor.
