Hi girls! I've attached my cycle (I've had to do it that way so you can see when AF Showed her face!) I've also attached a ovulation test taken just now! I've started spotting today brown discharge! And as you can see AF Is not due! Can anybody shed any light on what might be happening! All comments are appreciated! Thank you! Apologies for TMI!
