Pregnant and feel awful

I’m 12 weeks pregnant and before getting pregnant I was always up for sex, would literally jump on my bf. But now I’m pregnant:

I dont find him attractive at all.

Certain things he does repulses me

He irritates me

Don’t wanna hug him

Don’t wanna kiss him

Just arghhhhh 😠

I honestly do NOT believe I feel like this because I’m pregnant especially the not attracted to him part. I dont know what I’m meant to do. I’m at a loss!
