Hello, your symptoms sound like a urinary tract infection (UTI). The most common symptoms of UTI are pain during urination, increased frequency, urgency. There s a constant feeling that the bladder is full of urine even right after urination. Sometimes blood can be seen either macroscopically or microscopically. A urinalysis and culture can determine whether an infection is the cause or not. You ll have to do it before your period because it would be difficult and inaccurate when bleeding starts. I hope things are clear now! If you have further questions on this subject, I ll be glad to answer. Kind Regards!
