So, as I said af is due tomorrow, so I'm probably out...but I can't resist sharing symptoms anyway. On and off for the past couple of days I've had an unexplained backache. I've been getting cramps like af is about to arrive for the past week, but today they aren't there. I keep getting sharp pains on my left side that feel like O pains. And just now I noticed (apologise for the grossness of this one) I have thick, yellow cm. I just tested with an IC for the second time today and BFN.
