Disagreements in raising a child

Idk how to handle this. When me and my fiancé talked about having children we agreed on how we wanted to raise our child and now that I am pregnant my thoughts get shut down and his true colors are showing and he tells me "its my child". Which in turn pisses me off because it's our child and really I am the one doing all the work!!! It's his way or the high way it seems. Idk what to do there are some things he wants to teach our child that I do not agree with. And when we talked about it we came to an agreement and now he has changed his mind. Idk what to do ladies.......
