NC regular for anonymity.
I have absolutely always been regular as clockwork. I knew I was pg with pg1 when I hadn't come on by 2pm on the appointed day; tested positive at 4+0 on internet cheapies with pg2 and pg3.
I am four days overdue and still getting negative tests on ICs. I don't feel particularly premenstrual, nor pg. It is just like someone has pressed pause!
Please slap me with a wet herring and tell me to stop fretting. My brain has flown to the worst case, which is "pg but mcing".
