Hair loss during pregnancy?

Vann • Wifey 💑 and mom to Joey & Adrian 👦🏼👶🏼
This is my second pregnancy, my son is almost 2 and I'm 10 weeks 2 days with this one.
With my son, my hair grew like a weed and was so thick. This time around its falling out constantly. 
I was having issues beforehand with hair loss and was seeing an endocrinologist, but after multiple tests, everything came back normal and she just said "maybe it's stress" 🙄 
After I found out I was PG it became even worse and my hair Is already thin from the shedding before... I need to mention this at my next doc appt. b/c I forgot to before. Has any one else experienced this?
