I feel so moody

So scared of pushing my husband away because of my pregnancy induced insomnia, cravings of things that I don't even know I want, and the down right bitchiness excuse the language. I hope this pregnancy doesn't drive a wedge between us, we've only been married a few months so we didn't have a lot of time to be married first.... I just hope we don't lose the reason we fell in love in the first place.
