Pregnancy and Stress Hair Loss

Hi,
I am 4 1/2 months pregnant and just recently noticed a bald spot on the back of my head. I have very thick and curly hair, so it’s not noticeable and I have no idea how long it’s been going on and whether or not it is even related to my pregnancy. I am just concerned because it’s rather large and I am not sure if it will get worse. I know it can be caused by stress as well. I didn’t realize I was this stressed out! If you could help lead me in the right direction as to what the cause may be, I’d greatly appreciate it.

Thanks in advance.

Although pregnancy can impact hair growth as more hair goes into the resting phase of hair cycling, the presence of a bald spot probably indicates a cause other than pregnancy related hair loss. I suggest that you see a dermatologist. There is little I can do here through the internet.
