So me and my partner TTC my period was due 24th December eventually arrived 3rd January it's not a proper period though only light pink when I wipe, nothing on sanitary pad. Before my period I took a test when I was 5 days late (29th December ) which was negative. However I have tender breasts, sore head, itchy nipples, constipated and extremely fatigue . Has anyone else experienced this and what was your outcome ?
