Increase in discharge

Se

Sorry tmi. I'm 33 weeks today with di/di twins. I have noticed an increase in my vaginal discharge in the last 3 days. No blood or change im color. Also, BH have increased but aren't very painful. My MFM specialist says my OB can schedule a c section for 37 weeks but she thinks I'll be in labor by 35 because of my short cervix. Is the increase in discharge a sign of labor? If so, after how many days could I possibly go into labor? Anyone has any experience or advice? I'll be seeing my OB next Monday.

P.S. baby A is breech. And I'm not afraid of c section. I'll do anything as long as my babies are safe.
