This might be TMI, but… so confused

My husband and I have been TTC on and off for a few months now. In the month of JULY we baby danced 2 days before ovulation and day before ovulation. I confirmed with opk and my bbt chart showed the rise in temp. I was almost sure I would land pregnant with a BFP. I tested at 9 DPO and was negative with Walgreens brand test, No faint line. I was 1 day late with my period but when it came it was weird. It was a brighter red mixed with what looked like raw egg white CM, first day was less than what I considered my norm, 2nd day was super light, and then it stopped. On average my period are 4-5 days being pretty heavy. Should I test again? Or go to the doctor? Or am I just overthinking it? IM SO CONFUSED.
