i'm constantly nauseous, i'll get hungry and lose it after one bite. i won't throw up, i usually don't unless i'm seriously sick. my kidneys hurt, i've been drinking some  (not alcohol, liquids in general) but not alot. i'm bad about getting dehydrated. i've felt this way since the morning after sex and it wasn't my first time. it was protected, but i was a little worried about this feeling so i went and i bought a plan b pill and took it about 30 hours after. my right side of my abdomen has a pain thats always there but it's sharper pain at sometimes over others. it's bearable but i'm not comfortable. at first i thought it was a UTI, but now its a month later and the pain is still here. what do i need to do?
