I'm 26 had our baby boy 4 months ago. This is our second son but both pregnancies were completely different. I didn't breastfeed with our first because I was 19 at the time and placed him up for an open adoption(but that's a different story for a different time). Anyways I tried breastfeeding with our second but it didn't work out so I got my period last month but now I am three days late.  Is this normal?
