Impatient!

Hey everyone. My husband and I have been TTC for 3 cycles now, and i'm supposed to get AF on the 25th of Aug. Today i'm 10 DPO and for the past 24 hours i've had major dizziness and lightheadedness almost constantly. i tested yesterday (9 DPO) - negative. Tested again today - negative. I know i just need to relax and wait till later this week but i'm so impatient! My nipples are very sensitive and sore, but my boobs aren't, which is very unusual, as I usually have intense boob soreness in the 7-10 days leading up to AF. Anyone else super dizzy during their TWW??
