I am currently approx 8/9 days late for this months AF. I don't always have bang on cycles but because I track with Flo I know all my cycles for the last 8 months have been 31 days and if not its a max of 35 days. I didn't think anything of it as I started getting my usual tell tale signs from 1-2 days before - light cramping, tender boobs, headaches. When AF still hadn't shown on CD 36 I decided to test (I have 2 children already and have had 2 miscarriages) and got a negative so again just thought I was late. I'm now on CD 40 and for the past 7 days I've had on and off cramps really low in pelvis, burning breasts from my armpit to my nipples, low back ache and pain in hips (had hip problems in both my pregnancies) I've done another test today and still negative. With all my pregnancies ive been able to get a positive straight away with any time of the day urine. Anyone have any similar experiences?
