Hello girls. A couple of hours ago I noticed a few drops in my underwear and at first thought it was discharge because they were sticky. But now checking they dried completely, usually after discharge there's a mark, but here there is nothing. Could there be water leaking out in several drops? What should I do in this case? Should I call an ambulance or wait until it leaks more?
