Random Bald spot

Jade • ✨✨✨✨fraternal Twins ❤️

Ok so this is extremely weird idk if it’s connected or what I’m 5 weeks pregnant and I recently found a big ass bald spot at the base of my head it does not itch it’s not dry it doesn’t burn it’s just smooth I read online it could be Alopecia the bald spot is caused by my immune system attack my hair follicles I’m not 100% sure that’s what it is but i honestly have no idea what it is I have a check up next week for the baby and I’m gonna bring it up to my dr and see if she knows anything it freaks me out because never has this ever happened to me has anyone else experienced this or has this?
