I got it back when ds was about 15 months, and it was a little weird in terms of timing for a while. now, it arrives regularly but does weird tings wheen it gets here. I have a lot of clots (small ones, but lots) which I never had before I was pregnant. Also, it lasts about 4 days, stops for 2 or so days, and comes back on the 6th or 7th day for a day or two. Weird. I just assume it's because I'm still nursing. BTW, ds is now 2.5 years old.
