Anyone else having AF issues?

Jessica

so before I had my 2nd son my periods were always on time and I would bleed for 3 or 4 days and be done with it....After my 2nd son my period is very light spotting that is red and pink for 3 or 4 days but it's not enough to wear a pad with and I had one September 3 thru the 7th and again September 22 until tomorrow....is anyone else having these issues? if so how do I track my ovulation?
