I’m sooo confused

Okay to make a long story short, I’m having the sore boobs and the cramps of a period, yet no period. I’m 2-3 days late for my period but the only thing I’m having is white discharge. I’ve been dealing with mom and grandma in the hospital this week so I haven’t been sleeping too well and my new job requires a lot of movement. Could that be why? I did have sex the day after my last period and he pulled out and the tests I’ve taken have been negative. What are your thoughts?
