So Emotional!

Today I am 20 weeks, which this morning I was really excited for because it means I'm halfway there. I told my husband that our baby was the size of a banana and he seemed to dismiss my comment which made me feel a bit sad. He is normally like this, and regularly it wouldn't bother me but today it hurt. And a bit later he made a comment on how I have to find a job, which I do, and I normally wouldn't get upset over this but today it hurt. I am so so emotional, so after I drop him off all I could do was cry in the car on my way home. Are any of you feeling uncontrollably emotional this way?
