Trying not to get too excited...

Amy • Married💏 proud mommy to a bright baby girl 😍
I had a one day period almost 7 days ago. A day or two after, my period vanished-- I tested. BFN 😩 
I talked with my sister who said the same thing happened to her and she didn't get a positive until a week after her missed period. 
So she advised to take a test a week later if I still don't get my period. It's been 6 days and still no period!! 😊😁 
But I am SO nervous to test because that BFN is not very fun to look at. 
I'm feeling some symptoms but I know that it can always be in your head or be PMS.. 
So I need some positive vibes, tons of prayers my way please! 😁😊
