I know with me, sometimes my cycles are just about regular, sometimes they are totally off! My ds is 2 years and 4 months, so I would think that he has gone through lots of growth spurts (lol) and at times would nurse more than usual. It SEEMS that during those times, my periods turn up irregular. So, maybe it is just that your baby has been nursing more often recently. I would also just take another test soon...just to be sure though
