I know your hair freaks out and does all sorts of weird things. My mother’s went straight and her moms went curly and grew at insane paces... but all mine seems to do is fall out

My hairs always been thick and grew out to mid back and would stop but now it just falls out constantly it feels like. Or maybe I’m just freaking out about the quantity. Nothing’s changed in my hair routine and I still take a million and one vitamins. I’m 28 weeks along but every time I run my hands through my hair it looks like a German Shepard just shook and walked out of the room

Has anyone else had this happen before or know ways to reduce it?!?
