Huw much is too much?

My obgyn's booklet told me to contact the office when I'd have too much loss of white mucus.

But how much is too much?

Some white loss is normal.

But yesterday I went to the toilet and I had a bunch that ran out of me like it was pee.

Milky white runny pee...

I'm going in in 2 weeks and planning to ask when I'm there anyways, but also checking here in case it might indicate an emergency
