I would advice you to do it again because whether it had came out in a discharge form then it has started to work but, them came out therefore wouldn't of worked to the best it can. I've it keeps happening then i would make an appointment and just tell them it's coming out but, had a discharge then they might be able to give you something else or do something to prevent it happening.
hope i've helped.
I had that trouble it come out so I tried the oral version - canestan combi - oral
