Blood Spot

Woke up yesterday morning with c pap mask on, nasal pillows in my nose, and there were 2 little spots of blood on pillow case. No blood on mask, or my face, or anywhere else on my body just on pillow. Has anyone experienced this, I'm wondering where the blood came from? Thank you!

duplicate post and the first one was yesterday I think it was.

To OP....impossible to offer any sort of accurate response because we have no other information about your equipment.
Even then it would be difficult because no one here can see what you see.

I don't really have an answer for you. But it happened to me twice with the p10 which was the first mask I tried. I didn't like the p10 for other reasons, e.g., hose in front, and the headgear slipped since I have thick hair. Also, the pillows did not stay in place and would leak during the night. I kept fiddling with them. So I replaced it with an n30i airtouch nasal cushion. I do intend to try the p30i pillows though. The blood could have just been my nostrils getting used to pillows. The other change I made recently was switching to climate tubing. I don't think I really needed it. I actulally liked the cooler air and did not have rainout issues. But my respiratory therapist said she recommends climate tubing to all of her patients. Maybe, if you are not using it, climate tubing would help keep your nose moist. I am definitely not an expert as I have only been using a CPAP for a few months.
