7dpo but BFN?

I had a question. Does any of this sound promising?

5dpo- left side abdomen pain, (but this was the only symptom)

6dpo- nausea, extremely exhausted, achey mouth, and headache

7dpo- nausea, extremely tired, and taste buds are waaaay different, runny nose and no energy.

So the beginning of this week, I’ve been able to handle coffee with no problem. I made coffee today and I only tasted coffee and water, there was no sweetener I could taste. I was nauseous after that, an hour later I tried making some cereal instead. I tried a little bit of milk just since I was thirsty, and the milk wasn’t expired until the 30th of this month. I could not handle it, and at this point I just feel like I have a cold. My nose won’t stop running, and I am so tired I could sleep all day. I have no energy at all, my period isn’t supposed to come until next week but I just don’t feel right this cycle.

Does this sound like a good sign ?
