I'm 38 weeks pregnant and i've started getting clear thin but slightly stringy discharge when i wipe. is this normal or my mucus plug coming away?

"38w pregnant": The "mucus plug" may not be seen with every pregnancy, but at 38 weeks, the pregnancy moves farther down into the cervical canal, which can dilate the canal somewhat, enabling a "clear, stringy discharge". Usually at this point you are seeing your OB provider weekly, who will do an exam to see if you are close to going into labor.

Call your OB MD: The clear stringy discharge could be leaking or ruptured membranes. Call your OB MD and have him/her evaluate this situation as prolonged membrane ruptures can lead to intrauterine infections to the baby and pregnancy loss.
