Physically Uncomfortable

No matter what I do I just can't seem to get comfortable. I'm either too hot or I'm just like not sitting right or whatever. Idk. I'm super stressed out. I have emotions out the ass. I'm stressed out about literally crying every day because I want a baby but can't have one right now. I think everything could be a symptom of early pregnancy. I'm just so fucking sad and I just can't lay down comfortably. Been like this for months. Why is this happening?
