Has anything changed recently - for example, have you just gone on the pill, or changed your pill (as this can change the appearance of your discharge)?

I have had the type of discharge you describe - and (to my knowledge) nothing was wrong. Sometimes discharge changes at different times of your menstrual cycle (it's a lot thicker for the two weeks before your period, but thin, stringy and runny at the beginning of the cycle).

I also remember having that type of discharge when I had thrush (although it was lot thicker than you describe) - are you itching at all?

If you don't itch, it doesn't smell foul, you're definitely not pregnant and you don't have any other symptoms (pain etc) - I expect it's completely normal. Maybe just wear a panty liner.

Hope that helps!
