Pink discharge before period??

So for the last couple of days I have been having creamy discharge with a pink tint. Thought it was my period starting but it has not progressed. I have sore bbs which is normal for pms. I am cramping. Period should be here. But it could still be coming. I did have sex once with a condom. And once I unprotected but he never ejaculated. I am stressed and kind of worrying which will only delay it more. I feel like I cannot be pregnant, even though I know nothing is 100%
