Hi, I've recently been trying for a baby after my implanon removal on dec.12 ,2012 I got my first af jan. 12, 2013 the second was feb.7 2013 both have been 3 or 4 days in length. Now after doing period trackers and fertility trackers etc. My period was due march 5 it didn't come until march 11 and in that time I was experiencing mild cramps. Now I have dark bleeding with cramps I'm so confused.
