@Summer when I was in heavy training and competing I missed my af for about 6mths. Not sure if you are training hard etc. I am a clock work 25 day cycler, so if mine went missing I would be very very confused too. But Id be face planting the GP's door for a BT. I am very impatient, you are doing well. Our bodies cant always be explained, I guess thats why miracles still happen.
