White discharge

I feel like I always have an either sticky or creamy white discharge. It's usually creamy but what does that mean? Apparently it means early signs of pregnancy & I'm worried bc I let my bf stick it in me w/ put a condom only once last Tuesday & I've been paranoid about being pregnant even though I take my bc pills. Is my discharge normal or do I need to be worried? I have a little less than 2 weeks till me period
