Welcome to HCM.
Since you have been trying to conceive for only 5 months, you might as well get pregnant without any treatment. If one tries to conceive for 1 year and does not succeed, then we label that couple as a case of primary / secondary infertility
depending on whether they do not have any children or already have one or more children. To become pregnant you should have intercourse between 12th to 18th day of your menstrual cycle, day one being the first day of your menstruation
, provided your cycles are fairly regular. If after trying for few more months,you do not succeed, then you need to consult an obstetrician, get complete investigation done of both you and your husband, such as follicular growth study by ultrasound
, semen analysis
etc. and if indicated the doctor will prescribe medicines to assist you to become pregnant.
As for discharge, if it is not foul smelling, you can ignore it otherwise it needs medical attention.
