I'm also impressed with people hanging on to test, I am struggling not to crack open the FRERs now instead of waiting till tomorrow morning. Must... resist... 
I wasn't charting btw and hadn't done opks, as my wtf cycle was so long we just thought we'd have a low-key restart and just dtd a few times to get back into practice as it were. My only indicator of ovulation was a small amount of ewcm on CD20 so I assumed that was it. Now I'm really hoping it wasn't. Oh well no way of knowing now, I'll just have to wait and see what happens.
