12 dpo and negative. Could I be pregnant still?

I will say that my cycle is usually 28-32 days. I'm about 12 days past ovulation and I've gotten two bfn! I took the first at 8 dpo and the second yesterday (both digital though) I'm not having my usual period symptoms and my period is almost a week late now.
Current symptoms:
Frequent urination
Lower back discomfort
Increased appetite
Breast sensitivity (not intense)
Hot flashes
Mood swings
Bloating
I also ate something I eat often last week and it tasted "off" to me which is what really made me think. What do you all think? I'm gonna test again in a couple days with frer.
