Hi, I am usually a regular 28/29 day cycle and without fail AF shows on time. However, I am 3/4 days late and that has never happened since my cycle got back on track a year after my first born son. I have taken two pregnancy tests both negative, there is no sign of AF as I usually get backache that's when I know I'm coming on. I've got extremely tender boobs, spells of nausea, really tired towards afternoon and strange twinges every now and then in my lower stomach toward the left but nothin like AF. So I'm a little confused as to what's going on. I've also had a lot of discharge or just a feeling of being wet and there's not much discharge there, but what is there it's is quite watery. Could someone who had had this help please?? Thankyou. Sarah x
