Hello, my LO is almost 4 months old. I breast feed on demand and give 1 bottle of formula each day. My period has not yet returned. I have a perscription for birth control (Micronor) but I'm not taking it, mostly because I've been off the pill for so long that I can't remember to take it. Currently we use other methods to prevent pregnancy, and I'm just wondering if it's necessary? Is it possible to get pregnant while I'm not having a period at all? Perhaps this is a stupid question....
