Discharge??

since about the 14th of dec i have been having a runny white discharge with no itching and no smell, it did stop for the 3 days i got my AF, i got that the 29th of Dec. and it only lasted 3 days and was kinda heavy the first day and really light the next two days, and then when it was gone i started seeing a lot of runny white discharge.. again there is no itching burning, or smell.. it just seems like its a lot there more then normal. and not sure what it is, and can't afford to go to the dr.  i have been trying for about 2 months for a baby, so don't know if that will make things different, someone please help me
