Is it normal?

Hey!! Im 14 weeks pregnant this week , last week i went to the bathroom 2AM and something weird happened. Peed per usual, and when i finished looked in the toilet and saw like a brown discharge mucus thing. Tried picking it up but it dissolved. Never happened before and hasn’t happened ever since that day. Haven’t bled and haven’t had cramps. I know there can be a change in discharge and it can increase but when i saw it, it scared me (had a MC last year). Midwife says it doesn’t worry her.

Opinions???
