That is not always true. I think breastfeeding affects different women in different ways. I had a period one time after the 6 weeks and not again untill I stopped breastfeeding my daughter. And yes I breastfed her exclusively. Also I think it is like in the millions or close to it for an IUD to fail. I know it is not a 100 percent but it is pretty close. I plan on getting one of those after I have my son. You can take a test if you still feel uncomfortable but I wouldn't worry about it untill you had some specific pregnancy symptoms.
