at about 3 1/2 months mine started falling out. but no where as bad as that. I use to shed bucketloads, and whilst pregnant i only shed about 1/3 of normal. and now it is back to what it was before i was pregnant. My hair is very fine and thin anyway, so even though there isnt much of it, it is pretty evenly spread over my head itms...so no bald patches

hormones whilst pregnant are meant to stop it falling out (dont know why) which is why people say their hair is thicker and longer whilst preg. so when those hormones leave your body, it would start falling out again.
