Mucus plug?

For the past 3 days I’ve had consistently bad Braxton Hicks contractions but also have had this mucusy discharge everytime I wipe after a wee and am getting really bad stomach cramps. I’m 33weeks and 4 days but could this be my mucus plug? Not a very good picture but this is the sort of thing I keep getting, the flash makes it look a weird colour but it’s actually white colour
