Can someone help? I've been getting these weird pains all day in work, they're only lasting a few minuets then going away, AF is not due yet but my cycles are long (they vary between 37-40) my last AF started on the 6/12/18. Could this be implantation? I've never had this before and AF never comes early, as the days gone on it's gotten lighter to the point where you can hardly see it and then just now it's gone back dark X
