Have Urology Questions? Ask a Urologist Online.
Do you have pain , fever or difficulty in passing urine ?
Are there blood clots in the urine ?
Are you taking any blood thinners ?
Please let me know.
If it is just blood in urine with no other symptoms like pain, fever or difficulty in passing urine , then you can wait till tomorrow to see your doctor.Drink plenty of water and avoid straining.
If voiding difficulty/burning increases then you should see the doctor today. Probably you have an urinary infection and the aspirin has contributed to the bleeding.If you think contacting the doctor at night will be difficult in case any emergency comes later, then better sought it today itself.
If you have any doubts , please let me know.
