Caitlin • 25yrs old first baby due March 19th

does anyone have hypothyroidism or had it? I'm pretty sure I have it my moms whole side of her family has it and I have almost all the symptoms and I have had them since I was in high school but I always got diagnosed with other things and I'm gonna go get my thyroid checked but Im curious about what the treatments like and how it affects you and how soon it starts to affect you
