BFN at 10 DPO but all the symptoms

It’s a bit of a long one but I’m at a loss so any help is so appreciated!

Beginning at 5 DPO I started having extremely mild cramping. It was intermittent and I had a small streak of blood in the evening. Just on TP nothing in my panties. The cramping was continuously intermittent until 9dpo when I started feeling cramps that felt like stretching and pulling in my sides. Now 10dpo and I’m feeling cramps in my pelvis and back.

BFN this morning.

Other symptoms: random bouts of nausea, sore boobs, fuller boobs, heightened sense of smell, peeing constantly (every 2 hours at the least. Sometimes every 20 minutes), exhaustion (wanting to take naps/struggling to keep my eyes open), a sense of fullness (struggling to eat meals), halfway through eating something the thought of eating one more bite makes me sick to my stomach, dizziness when moving around, out of breath easily the last two days, and I have woken up with a headache every day since 6 DPO.

I have a strange overwhelming sense that I’m pregnant even with the BFN this morning.

Any ideas 🤣
