Has anyone has a beta done at 8dpo and count was <2? Then later was actually pregnant?

Please share with me if you've ever had a blood test done 8 DPO or early, and was told you're not preg. I feel I am I have these blue veins in my Breast and they're getting darker and darker by the day. They also did an pelvic ultrasound. They didn't see anything which I don't think they would have anyway this early. I've had really bad pressure on my left side so they wanted to rule out anything serious.
