Hormones and SO

Just wondering,

With the hormones being out of control some days with pregnancy. Us sometimes feeling lonely, sad, out of control and then super happy again.

Do you guys tell your SO everything that goes into your head on a day to day? Do you guys talk about what you are feeling and going thru?Is there some sort of understanding from his/her part?

Do you believe you handle it well? Do you feel well connected or do you just blow up one day and expect him to know how you feel?
