Good lord what is going on????!?!?

So last sunday I missed my bc pill, little blood mostly brown discharge came which I expected from the last time I accidentally forgot, however since that, the past two days in my vagina in the kind of back (thats where it kinda feels like where it is) up in it a little, it feels like an itch, but its more like a sore itch, where its not the itch that you need to itch that'll tickle then go away or you will start twitching until you scratch it, this is more of a tender sore itch, and I woke up i nthe middle of the night trying to get rid of the itch, went to the bathroom (peeing helps temporarily) and wiped and kept rubbing the toilet paper really hard because it felt a lot better when I would do it and it got really awful, so I have vaginal wipes to clean when something is off, so i used that, went back, still felt bad, so I took off my pj shorts and underwear and instantly fell asleep, but when I woke up this morning it is still there. Haven't changed any washing habits, still use vaginal wash in the shower for that specific area. Do i just need to drink a lot of water, restore my pH or something and flush out my urine system?? Idk what it could be help please its super uncomfortable!!!!
