I had unprotected intercourse in December. I had urinalysis first week of January and found out that I have Pyuria. I had my period in the 2nd week of January, it was 5-day menstruation. But I haven't had my menstruation in February and until this month, March. I do not sleep at night, only in daytime and 9 hours I am facing a computer. I am asking what probably is my problem.
