LOL! In the last 10 years I have had 4 periods.
One in August 2005
One in September of 2002
One in Dec of 1998 and one in Jan of 1999.
Since this is our last child I don't know what I'll do when my AF returns to stay. But I won't have to worry about it for at least 18 months. I didn't even see my AF before this child was born; I got pregnant without it returning. (Well, it was obviously on its way, lol!)
Anyhow, if you are EBF it would actually be unusual to see it this early. I have EBF all my kids, but they also all slept 5-7 hr stretches at night, almost from the start, and still no AF.
