Spotting 3 days before period due

I'm 11 DPO and period set to start in 3 days. I wiped and it was pink but nothing more came from it. Had sex on day of ovulation and next 3 days. Pull out method was used. I'm wondering my chances of being pregnant vs. starting my monthly. It's been a very stressful couple weeks as well as struggling with depression so that could play a part also.... just made me freak a little and I have no gfs to talk to about it
