Hair loss and pregnancy?

Lor

Okay I've always been told that when your pregnant your hair comes in long and thick die to all the hormones. Well my first trimester everyday I had chunks of hair falling out and now at my fourth month it's not falling out anymore but it's not as nice as it was. All my blood work came back good nothing off. Curious if anyone has had this happen? My hair is long and I want to cut it short now since it just doesn't look as nice as it did.
