Haven’t Started Period Yet

Alisha

I am still breastfeeding my ten month old. He’s down to morning and evening feeding. I started my period back in September and in October I was 8 days late but then I started and had a normal period. This month I haven’t started yet and today makes 2 weeks late. I have took a pregnancy test every day since being late and all are negative. I honestly do not think I am pregnant but I was trying to make sure. Has anyone had this happen? I’m going to call my OBGYN tomorrow but was wondering if anyone had the same thing to happen. Is it going to be irregular because I am still breastfeeding?
