So strange!
I too was due on two days ago and am still waiting in vain. I'm just hoping it's a couple of days late or something though.
I had the cramps which felt like I was about to start, but then they went and no period. I've been feeling sicky and threw up yesterday, but that may have been dodgy food. I'm going to wait another week just in case I got the wrong week completely, then after that I'm going to buy an early pregnancy test.
I'm not sure whether I'm excited or scared, but either way I'll be fine with the outcome.
I suggest one of those early response pregnancy tests, and what I always found worked if my period was late or slooooow, was some vigorous exercise and a hot bath, Always started me off
Good luck, and fingers crossed for you too Shhhh!
