My doctor is probably annoyed with me by now so I haven’t ask her but just last week an half I’ve been having a lot of discharge and I don’t know why and I haven’t had my period in 4 months and I’ve taken pregnancy test an all 6 of them were negative but now I’m discharge to the point it feels like it’s so much it goes halfway down my leg. I had discharge before but not this much. Would any one you have any idea what’s going on. An sorry if this is gross.
