Thinking back it would have been for the first few months post partum

After each pregnancy I’ve started losing hair around the 3-4 month post partum stage and lasts 2-3 months.

I have had two children and my hair has not fallen out or thinned during pregnancy or after the birth, I have had many friends who have had children and only one of them had their hair thin a little during pregnancy however after giving birth this stopped. I think it is different from person to person.

i didnt notice a significant hair loss in any of the prenancies

Like 3 months. I lost hair 3 to 6 months with 4 months being the worst!

It usually thickens up during pregnancy and falls out after the baby is born. At around 4 months with both of my girls I had bald patches at the front for quite some time (around a year).
