Hopeful

So i posted the other day about my HCG of 8 which was done 9/2. I had it redrawn today waiting for results. But my strips show such a progression even just from this AM(the middle one) to tonight's (the bottom one). The top was the day it came back at 8. Am I dumb to be relieved? The nurse told me it was probably a chemical and I'd lose it because the level was 8. Im thinking it was super early. I ovulated 8/22 despite my period being due 8/26 I ovulated later than normal for me. So I'm thinking ill only be measure 4 weeks so a week and a few days before what id be by period. Thoughts?
