GIrlsailir, the WTF cycle is very aptly named, anything can happen so it's hard to try to apply the usual rules! I had one AF 5 weeks after when I still had hcg in my system, and another time dead on 28 days. Don't panic!
Teenie hope AF 'resets' things for you. My body seemed to need an AF to finish off the mc, if that makes any sense. New cycle, new start.
This thread is brilliant, feels more real than RL at the moment, and I totally agree that BFPs on here are not baby bombs, they make me happy and give me hope. Please keep sharing what's happening in your worlds 
I spoke to my gp this morning who, bless her, was lovely and supportive and agreed she's confused too and can't get the numbers to add up (glad it's not just me!). She's put me back into antibiotics (strep b detected on Thursday's swabs). Oh well, at least I'm a mystery 
Just had 3 hr sleep on sofa. Sleep is good.
