Any moms go through this?

Do any moms have any experience with this. I had a my second baby 14 months ago and just started having my period again maybe 5 months ago, my periods have always been fairly irregular but only by a week or so either early or late which I believe is fairly normal. But this past period I only had spotting which isnt normal for me and it was only for a day and now I haven't had a period in 21 days. Also I didnt have this with my first. So anyone else have an experience similair?
