In my first urine test they found blood in urine. So they called me next day again to redo the urine test. I do not have PCOS. After researching on internet I found that blood in urine may be found for various reasons such as Urinary tract infection (UTI) which is very common in females, excessive workout just before test, etc. I guessed I had mild UTI because I had it previously during pregnancy. As a solution I found that drinking lots of water, water melon, cranberry juice helps in cleaning the system. I drank lots of juices and water before the second test day which was only a day apart from my first test day. Just like you I was also worried about the result. However, I passed medicals in 2 weeks after submitting my file. You should be doing fine too. Wish you good luck.
