Thanks for replying Teme, I was starting to feel I'd touched on some sort of "don't go there" subject!
I feel I know nothing about what's happening to me! I'm waiting to get my test results back, but the docs think the watery discharge maybe a side effect to the treatment (Dalacin V cream) I'm on for the BV which finished its course last night. They said over the wkend if it got worst at any point and I was worried to call the hospital, it did get bad on saturday but I didn't know if it was bad enough to call the hospital; I didn't and I felt better in the morning. I felt good enough Sunday morning that I slowly woddled around the market for less then 30mins; this proved to be borderline painfull and very wet (but I picked up a couple of things for the baby's room so I was uncomfortable but happy). My partner says I should relax and enjoy resting, but I'm a stressful rester; I get bored and my bum gets sore! If it is a side effect to the treatment then hopfully it'll clear up over the next couple of days.
I found that when I was researching BV I was more interested in real peoples experiences rather than fact sheets, however there isn't really that much stuff that covers both BV and watery discharge (whether they're related or not I don't know). So hopefully even though this thread has no real answers yet, it may work to just comfort others who are having the same experience!
