I have a fairly regular 28-30 day cycle and am now on day 26. I have been extremely tired, irritable and moody this week for no reason. Also had aching behind my hip bone on day 22 and the past two days I've had brown tinged CM when wiping and last night one drop of bright red blood. No blood on pad when I woke up this morning and now very scant light brown when I wipe and an achy back (I get this with my AF) I don't feel like I usually do on my period but if I'm not pregnant, I'm worried as to why I've had such a short cycle (I've been tracking for almost a year!). I'm desperate to fall pregnant so it could be wishful thinking and I know I'll find out either way in a couple of days but I'm very impatient! Has anyone experienced something similar?
