..Just what I thought

Bought 2 tests when I picked up Dan from work last night.. Took one last night before bed and Dan and I both saw 4 little blue dots where the + should be... So we were like oook is it yes or no?? .. So I tested again this morning with my 1st pee of the day and it was a big fat negative. Just like I thought. But still no period. WTF!? It says that if you get a negative and you still don't have your period test again in three days. So I guess I'm waiting.
