I have had random cervical mucus (like egg white) which has lasted several days or been a bit dried up. It is a sign of higher oestrogen levels (but not necessarily ovulation- you need a temp rise as well for this)
I have also had watery discharge, which is different. Mine came after a rectocele repair, so I had stitches up the back of my vagina. The first time was a couple of weeks after the op, I had antibiotics and that seemed to solve it. I had an inconclusive swab, where the doctor thought it looked a bit thrushy and was a bit offhand over the wetness. The consultant said all was ok, and when I said I had had some dryness (labial skin, v dry and itching) he put vagifem on my letter.
The discharge came back and I tried canesten which helped. However, it came and went and came and went, the discharge got worse - panty liners were no good. It then turned pinkish and I was uncomfortable sitting again, so, fearful for my new scar, I saw a locum and said I had no idea if it was infection, thrush or meno. He took a swab, gave me ab cream and said I should be taking the vagifem. The swab came back ok, I picked up the prescription for vagifem.
It went and has not come back for a year
