Should I test again?

Nikki • Mom to 7 year old girl and newborn boy!

AF came to visit on June 3rd, but was rather light the whole time. Usually after AF I have no discharge. I tested the day before and got a BFN, so I continued as normal. Now I have a medium amount of creamy discharge, which again, is pretty weird for me right after my period. Should I test again? Is it possible to have a light period and still be pregnant? Thanks!
