clear watery discharge during AF

Christy
Sooooo....I left BC 10 weeks ago, after 3 days of spotting it looks like AF has finally arrived for the first time (I've had one day of medium flow, hoping it continues) however this morning i jumped out of bed as it felt like my tampon was leaking only to find a large amount of clear waterlike discharge, is this normal? On BC this had happened before but not such a large amount.
To be honest I'll happily deal with it just to get regular again.
