Creamy white discharge

Okay so I can't remember when's the last time me & my boyfriend last had sex because we have been trying to conceive but my period is supposed to come tomorrow for 3 days now I've been feeling like I've either started my period or pissed a little in my underwear & I'm experiencing weird feelings in my uterus But when I go to the bathroom there's white creamy like discharge in my underwear I'm freaking out it doesn't smell or anything like that someone help me please
