I understand the anxiety now! A couple days ago, I was supposed to start, but instead I just got a little light spotting. What really tripped me was my husband made a hot dog and I almost threw up from the smell, which has never happened. There were other symptoms as well, and I knew it was too early to test, but I was too impatient and it was a negative... So I have to wait a couple more days before I check again. >.<
Hope it goes well for you!
