wondering

Logan • I`m 19 and have a finace a mommy my little guy was born in October 2016 growing to quickly already
My period is supposed to be in two days and I've read when you have thick creamy discharge that should be before you get your period but it should be clear by the time you get your period 
I wonder if that means pregnancy 
Because when I was pregnant with my son I had thick discharge before I was late with my period 
Opinions?????!!!!!! 
And also my husband and I had had unprotected sex after my period about a month ago
