Is there still hope???

I am 3 days away from AF and 11 DPO. I took a test yesterday because I was convinced I would see something.

But it was a BFN. I was having back pain, fatigue, weird nausea/headache, and discharge not consistent with typical ovulation or period prep.

Today it is so much worse. I feel like my head is swirling and I feel like I’m going to vomit at any minute. It’s almost 11 am and I am still in bed because I can’t get my body to move.

Does this sound like it could be pregnancy symptoms? Should I just wait and see if AF passes me by and then test again? Or is it probably something else-like a sickness-because this is definitely not how my body feels before a period.

I don’t want to get my hopes up-that’s why I’m sort of convinced I’m just getting sick.
