So last month I got a positive the day before AF. The next day it was slightly darker... Then that night AF showed up. Took another test 4 days later and negative. Now I am having a "letdown" feeling... Breastfed both my kids for a little over a year each... But anyway, there was a little milk... Now I guess my question is, is it just from the pregnancy that I lost or should I call my doctor? Wanting to continue to ttc.
