caught husband watching porn ...

I caught my husband watching porn my first reaction I was screaming and yelling I felt so hurt. Right now I'm 5 and a half months pregnant so It don't make me feel any better ... our sex life right now has been horrible due to the fact I have pains all the time and still very nauseous all the time... should I feel upset and mad at him ? Or it's just a normal thing guys do it's not like he's actully cheating seeing another women and sleeping with her right ?? ...
