Эмоциональность, кровь, боли в ногах и частое мочеиспускание: что это может быть?

Not sure if this is allowed or not

Okay I tested negative on the pregnancy test this past Saturday but I have been so emotional for like a straight week what is this from like I cry over everything. Am I crazy or what’s going on? I should have done got my period I haven’t yet but when I wipe there’s a little blood on it but it’s not an actual flow. Also I just started hurting in my upper thighs for no reason and hurting so bad I can barely walk. Im constantly peeing,constantly hungry. Im freezing one min burning up the next. What could this be? Last week i was spotting light pink is why I went to be pregnancy tested Saturday. I also should throw in there when i either do spot pink or there’s blood on the tissue it’s not everytime I wipe #myfirstpost
