Is this bad or am I over reacting?

I am married. My husband and me got into a disagreement. We were fighting and I went into the bedroom to calm down. He came in and pulled my pants off and spanked me. Then I got upset and turned around. He pulled my panties off then he forced me onto the bed then inserted his penis into me. I didn’t fight him off but I told him to stop. He is so much bigger to then me and I’m also pregnant. I laid there and took it but was crying. As I cried he smacked me and told me to shut up. Was that rape or not? I did say a few times “I am not consenting to this.” But the weird thing was I got wet... I hated it but I got wet. Is that rape? Is it wrong? Do I have a right to be feeling upset?
