Looking for some advice. My husband and I are TTC baby number 2. My last period was 17 August, I ovulated last Friday and yesterday I had some light spotting. Today it's gotten heavier and I have mild cramps, still seems too light for my period. My problem is my periods have been totally irregular since having my little girl so I have no idea as to what my cycle is or when I am due my period. Could it be implantation bleeding or just a light period? Confused.com.
