its my second round on the depo and my first scare while on it, and i did have Ecoli poisening, and am now going to the doctures for my kidneys im only 16, after working in the garden my lower back hurts, im constintly tired, and cramping a hole lot, i ache and i have pains, all in my hip area, its too early for my period though it does seem to be comming earlier and earlier, iv been very very moody, and after working in the garden i forgot to wash my hands and got spray nine chemicals in my system, so i guess these all could be factors, though i have gained 5 pounds, but lost my pot belly i want to know whats going on and why i feel so week. am i preg? am i sick? what am i?
