Hi dear..if you are still having burning micturition alongwith frequency it s better to get a urine routine examination done with culture sensitivity if required and take antibiotics according to that..in addition you should take plenty of fluids, syrup alkasol and fosfoe sachet just once.. If you are facing problem in conceiving even after multiple attempts of unprotected sex for a year or so, get a complete infertility evaluation of yourself and your husband including your serum tsh and serum prolactin, tubal status ( HSG)etc..you would also require a gynecological evaluation to rule out PID..
