I had an UTI and the first medicine for 7 days did not clear it up so they gave me a new one for 14 days. I felt better. Two days after taking the last pill, I saw some red on my underwear and had stomach cramp. I have not had any red stains on the underwear since but when I use the bathroom , I see red , sometimes bright but mostly very pale in color. I had put in a tampon and found some red come out on it. Can this mean that I have cancer. My last period was at age 53, I am 55. About 14 days before the red stuff, I was at the doctor and I told her I had a milk , gooy discharge like I used to get when I ovualted. She took some kind of sample of my vagina and said I had some normal bacteria that was overgrown and gave me a supository for 3 days. She said I just had a UTI but now I am very worried because of this red stuf, I call blood on the toilet paper, today is Sunday and it started on Wed, afternnoon, 3 days after I took the last anibiotic. I am worried , do you think I have cancer.
