34w4d and sharp pains in crotch! Thicker discharge also today!

Sharp pains in crotch area, leading up to groin when walking or being active. I have noticed a thicker discharge today also and every time I wipe. It has went from clear (egg white) to a thick white discharge. Does the pain mean dilation? Losing pieces of mucous plug also? I don't have my next appointment until next Friday at 36 weeks!
