Hi goodmorning. Im 17 yrs old and I just had (or still have) UTI. It started the other day when I was constantly peeing, the urge to pee but nothing's there and then the pain after peeing. I went home immediately, but the pharmacies were closed already so I took medicine the next day. The med that I took was Rifampicin, that was what my grandfather gave me (im living with my grandparents). He also said that it had side effects of red urine. I took 2, one in the morning and one in the afternoon. All of the pain went away but the red urine hasn't, and I'm just confused if its my period (i'm supposed to have my period this week, im a regular) or if its still the side effect of the drug. Please help me? Thank you and God bless.
