I am 33 years old, 5 children, 1 abortion many years ago, Never been hospitalized for anything other to deliver a baby.Nothing other that a the flu last year. No past health problems. I hurt my back about a week ago picking up a heavy object, went to the hospital and they gave me a muscle relaxer and some pain medicine, now I am having a cramping in my left pelvic area along with the back pain . I had intercourse last night and noticed a light bleeding when I wiped, but now it s gone. Do I have an infection? My tubes are tied ,so I am not pregnant.I have nt gotten my period yet, which it usually comes on around the second or third of the month. Since taking the Oxycodone and the Flexerel I have been a little constipated. It has been almost 2 days since my last bowel movement if I don t have one today.
