9dpo sister made me take pg test getting discouraged now....?

the earliest many people get a positive is at least 10 dpo, but I would test again in a few days to be sure. But there is a chance, don't get too down on yourself. And a shift in hormones would cause all the symptoms. Maybe test with your love and you can find out together. But stay positive, and hopefully things will go right. Good luck and baby dust
