Period or pregnant?

I’m 13 dpo and my husband and I had sex 3 times when I was ovulating. I am supposed to start my period tomorrow but I still have a lot of white/creamy discharge. I’ve had mild cramps off and on for 2 days and I never get that before my period. My boobs are tender and I’ve been super bloated. Is this just my period or should I take a pregnancy test?
