Answer: Hi. Blood in urine could be because of
1. Intercourse the previous day
2. Urine infection
3. Baby related
If it's just one drop, probably urine infection.
1. Cloudy urine
2. Pain while urination
3. Burning after urinating
4. Back/lower belly pain
5. Fever or feverish with shivering
If so, a simple urine test can confirm. Your doctor can give medicine for clearing that infection. Also, drink lots of buttermilk, and tender coconut. It will help flush out the infection.
If you observe more bleeding, or brown or red discharge, or a popping sound and then heavy urination, please visit the doctor immediately.
