My period is supposed to start on Saturday. I have taken a few tests already because I just CAN'T help it. All were negative except a second line (very dark) showed up on one of the tests after the testing window.... of course. But just wondering how many of you didn't get positives until after your period was supposed to come and got negatives on all of the early tests you took. I'm probably out for he month, but hey, one can hope, right!?
