Can someone help? I was getting these weird pains all day in work last week, they was 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 day went on it's got lighter to the point where you could hardly see it and then just went dark again? I’ve had nothing since and it only lasted about 2 days x
