help ladies! so I got my period Sept 15 ended September 19 it was not a lot it was light but still had blood. I don't know what to thick because all this time I been feeling nauseous and for some reason I'm having cramps always also a lost of appetite for zure! I usually eat a lot lol but I just don't eat and nothing seems appealing to me. also my boobs have been hurting and last I been noticing I been peeing more lately what can it be ?
