I'm confused! I'm 99% sure I ovulated, all the signs were there, cramping, EWCM with pink blood, head aches, all sorts. That was on 16th March, AF was 5th, so that works out. I should have AF back now, but nothing. Got a lot of lotion like CM, unusual for me. I've got pains in my uterus. when I make sudden movements, cough, laugh, walk.. Anything. Cramping all day on and off, but no AF, nothing?! Yet a pregnancy test is negative. Could I have ovulated, sperm fertilised egg and its only just implanting? That would explain pain but negative test. I'm baffled.
