IDK what to do i’m really confused

Last year hasn’t been one of the best year of my life ( I guess for almost of us). Well while trying to get back my relationship back as before, idk but still seems is not working as i was expecting. Finally my wife now is pregnant after 2 years of trying. I’m very happy finally we did it, for real. But between us i don’t have so much happiness as before. I don’t want to break up, I want be back as before. Now with this pregnancy due to hormones l, due to nausea.... basically i fell always a part. We are living a particular situation in last month and I’m thinking.... ok is just period... will pass. I’m worried if is not like this? If I’m not the right one for her? I was expecting the pregnancy in another way after 2 years, to share more, be close... but i have impression now we are like friends not couple. Every day I’m reading something t understand if is only hormonal and be sure that is just for this time, but this is killing me. Every time a see pictures of happy couples where they share love for this amazing Gift. I know she is passing a tough period and I’m proud of her..... i just need be more close....

Sorry guys getting depressed and anxious!!

I hope all the best for my wife and the baby.
