We've been at it for over two months now, which means that the day of my hair loss is approaching (( I'm expecting it in about three months after giving birth, as I lost a lot of hair during my first pregnancy, even down to bald spots... Now I'm taking calcium and praying it will pass. Girls, tell me from experience, does this depend on pregnancy or is it just my individual nature and what's more likely to happen with the second time around? Who has experienced this?
