TMI........

So I had something gross happen to me earlier around 9 I was washing dishes & felt something going down my leg so I went to the restroom and it was brown watery discharge a lot of it and I freaked out because it has never ever happened to me then when I wiped i noticed I was spotting a little then it just stopped has this ever happened to anyone else && should I be worried or is it normal I should be starting in soon so I’m not trying to think to much into it but I can’t help but be worried like I said it really did freak me out though

Any advice please?
