I don't know if this is entirely related or not, since I've been drinking soup a lot recently too, so maybe not. But just now, after
I went to pee, I felt some discharge
come out so I took a tissue to wipe it as usual. But the discharge was a really dirty yellow colour. Then when I wiped again, there was some blood in it. When I wiped again, it was all blood. And right now I'm not bleeding anymore, but I'm not sure if this is the start of my menses or not.
