Scared of sex and orgasm

I’m 6 weeks 2 days pregnant today.

My husband and I have sex maybe 1-2 times a week, but I can’t fully enjoy it because I’m worried something bad will happen.

I haven’t had an orgasm in over 3 weeks.

I don’t really have a sex drive at all and haven’t for about 2 weeks. But I’m so scared that I’m going to start bleeding after.

Can anyone put my mind at ease? Or has anyone ever felt the same?
