Weird Discharge after Internal Ultrasound

Hi everyone. I’m 23 + 3. I have biweekly internal ultrasounds to check my cervix. This discharge popped up after my ultrasound today. At first I thought it could be some toilet paper but it definitely isn’t. No smell, no pain, no itching. Just weird crumbly discharge.

Normal? From the lube?

My discharge was it’s normal milky white before the ultrasound.
