We're trying to conceive, i was10 days late and finally came on, brown at first then dark red, now it's quite heavy, but no cramps at all?

Period?Ectopic Preg?: While you may have had a fertilized egg, it seems like it probably failed to implant and thus your period is a little late this month. That being said, there are a number of factors that can affect your period including stress, diet, and exercise, just to name a few. I'm a little concerned about the amount of bleeding. If you are going through more than a pad an hour, I'd get seen right away.
