i'm pregnant

i become a mom quikly,i'm pregnant.In the first three months,i usually feel tired,and easily get angrey.Feel queasy or nauseous.But now i feel better.

I would write the passage this way.

I'll be a mom soon.  I'm pregnant.  For (or: during) the first three months I often felt tired, got irritated easily and felt queasy and nauseated.  But now I feel better.

The words "nauseated"and "nauseous" do not mean the same thing, although many Americans seem to be unaware of the difference.  "Nauseated" means SUFFERING FROM nausea.  "Nauseous" means: 1) CAUSING nausea or 2) sickening.) (like a nauseous odor)
