What Causes A Vaginal Discharge After Periods?

I am worried of a certain discharge from my vagina. it happens continuously..starts after 2~3 days of my periods and stays till 2~3 days before i have my periods again. the discharge also reduces at the end of my cycle.Sometimes its transparent and stretchy and sometimes its white and stretchy. Sometimes there is odor and sometimes not. But mostly there is no odor from the discharge . because when I smell it separately there is no smell but there is smell down there. I am trying to conceive . Pls let me know if this is normal or some problem is with me.
