I feel I messed up

So my husband and I where talking that if we got pregnant it would be okay and that he wouldn’t be mad bc it’s not like we did anything to stop it well now I’m currently 4 weeks and 6 days and he won’t talk to me like he is mad and that it’s my fault and I don’t know what to do I feel like I really messed up and just went with my gut and never should have believed him I just really needed to vent I’m just so sad 😞
