My lower stomach hurts all bottom front up to my sides. my back just in the middle a little bit but might be because i was in bed all day.

Many possibilities: I think you said you had a period a week ago, but you should begin by confirming that you are not pregnant with a home pregnancy test. If not, then most likely possibilities are urinary tract infection - normally you would have some discomfort with urinating and change in urine color/odor - and sexually transmitted infection - usually would note new vaginal discharge.
