7 dpo and going crazy

I'm 7 dpo and hate the waiting game. I had a miscarriage last month at 5 wks and got an opk to see if those things worked and to start trying again sooner. Last Wednesday was a definite ovulation day, no mistaking it. I've been feeling off and just weird lately (not like usual before a period). Hoping I'm pregnant and it sticks and is healthy because this will be our last one. I want my 2.5 yr old daughter to have a sibling (sooner rather than later). Fingers crossed and baby dust to all!
