I've been getting that lovely white discharge too the last few days. Its pretty normal, I've had it in my other pregnancies as well
I'd keep an eye on the period pain. Maybe rest for a few days. Make sure you don't push yourself.
I felt some pain a few days ago after walking down the street & taking the kids to the movies, so I know I gotta start taking it a bit easier.
If it doesn't settle, I'd go in & get checked out, jic.
