should I test now or wait a little more

Vilma • Had a miscarriage in October 2015 and a stillbirth son in February 25,2017. My heart is ready to try again. Rainbow baby due July 2018 👶👶

So we've been trying to conceive since June of this year and so far no success. period is due today and so far nothing yet, but I noticed I have a. white creamy discharge. has this happened to anyone? Should I take a pregnancy test now or just wait a couple days more?
