Thanks for the query.
I first congratulate you for reducing those 30 pounds which in turn has regularized your menstrual cycle.
Your symptoms of frequency of micturation suggests UTI-urinary tract infection
Get your urine microscopy, urine culture done.
If found to be positive, start on antibiotics depending on culture and sensitivity report.
Drink plenty of water.
Have citrus fruits rich in vitamin C
Hope this helps,
