Sounds like cervical fluid, which is perfectly normal around 2 weeks from getting your period. If you were trying to get pregnant, this is something you'd really want!! The watery cervical fluid allows sperm to swim more easily to your ovaries, and therefore you would have a better chance of getting pregnant now if you had sex. Some women try to do everything possible to get this - what is referred to as "egg white" cervical fluid - drink lots of water, take robitussin
for example. If you found that you were drinking a lot of water the past week or so, maybe that's why all of a sudden you discovered it? Also, were you on the birth control pill? If you were, then went off it, you'll find that this happens.
