Try to relax. Go with your endo, and even get a second opinion. Immune disorders typically can be controlled to help you manage better. Do your research, get all the tests, and double check with another doctor before trying treatments.
I have had some mess me up. Working with a great endo now, he has improved my world!!
I do have to watch what triggers it, usually extreme stress, to much exercise, limit or cut out sugar! You will learn how to manage-but you need to relax
I know with babies that is tough, that is when my disorder came out. Good Luck!
