Early period

Katie • Hello all! My name is Katie and I have been married to my husband for 2 years. I have pcos and TTC.
So, I'm not supposed to start my period for 7 more days. But the last 5 days, I've been bleeding. I figured it was just ovulation bleeding, but I'm not sure anymore. It's super dark instead of normal, red blood but There also have been some clots that I've noticed..
What could this be? Cld it still be ovulation bleeding or is it my period?
