Cannestan Combi Pessary and Cream - did the tablet actually work? (Vaginal thrus!

Ok, just before bed I managed to insert the tablet into my vagina in the hope that it would just simply get eaten up by enzymes and work 'behind the scenes' but after feeling slight discomfort of it against the inside of my vagina I needed to pee (strangely, and I don't know why, I always need to pee every ten-fifteen minutes when it's late and I'm tired but can't get to sleep) so I went to urinate. It was hard to urinate at first so I returned to my bedroom, tried to sleep, couldn't and needed to pee again. This time I still struggled but then I felt the tablet suddenly disappear and I took a look to find it hanging from the vagina. I had no other choice but to discard it into the loo really because it was wedged in there and I had to use toilet paper to get it out. It wasn't re-usable because it had been eaten at the edges and looked 'soggy' in a way. Sorry to start such an embarrassing topic but I need help. Does this mean that perhaps my body knew I didn't need it (in this case, maybe my prediction of having thrush/yeast infection was wrong and the creamy yellow discharge and pretty strong fishy odour is just unusually normal for me?) or did it only need to use a small amount of it (hence the 'nibbles' at the edges (meaning that it should be cleaning out any infection/problems down there)?

I get discharge at least once a day really and I thought it could be thrush because being a teenager, what else can I do apart from wear tight jeans? I also don't want everyone to hear and mock me for changing pads in the school toilets as it's a unisex toilet and none of the toilets in school have music in the background! I recently went for a pee again and just as I was about to flush, found that my urine was extremely clear..almost matching water colour. Does this mean it's working?

Thanks SO much for taking up your time to read this and any help will be SIGNIFICANTLY appreciated! Thank you! <3
