30 weeks but hormone are on another level need some advice

So I found out I was a little anemic and the past week or so I’ve litterally been so tired I haven’t really left the bed. Also notice I’ve been extra emotional. My husband thinks there might be something wrong. Cause everyone keeps saying I should be normal this last trimester but this whole pregnancy has yet been normal. With extreme morning sickness and what not. Doctor says things are going well but I go threw crazy waves of emotions is everything good? Should I ask again?
