Yes... It has happend to me in everyone of my pregnancies (3) and I have very thick hair so I lose a lot there is hair all over everywhere lol
Its different for everyone. My hair loss actually slowed down in the firs trimester, but when I got to the second trimester, my hair started falling out real fast. I also started growing a lot of body hair right from the beginning of my pregnancy.
my hairdresser told me your hair usually stops falling out while pregnant, which is why you notice it falling out alot after delivery. I guess everyone is different though.ask your Dr see what he or she says!
I had the same thing at six weeks pregnant until recently (13wks)
