I feel like a bad mom

I’ve prayed for this baby and I finally am pregnant 5 months and I’m miserable I feel like I’m not giving my baby enough because I throw it up all day I spit constantly I can’t have a conversation without spitting 😓 I feel like I’m failing already ! I never expected things to be this hard on me I just feel like I’m drowning and he’s not happy with me because all I do is throw up everything 😓 it’s really just started though.
