Am I getting into depression? My head.

I am a 24 year old female, married and now 2.5 months pregnant. Most of the time I feel tired and fatigue which could be normal during the first trimester. But I am having sudden emotional breakdowns and I avoid talking to people. I used to love music, dance and reading but now I can't get myself to even get up and do any of these anymore. I am still unattached to the little one inside and though my husband is doing his best to manage his work and taking care of me, I keep blaming him and getting into fights with him. I feel horrible and guilty about it most of the time and I feel trapped in a loop everyday. I cry a lot for no reason and sometimes I cry myself to sleep. I can't wake up and just want to be on bed all day. I want to come out of this feeling and stop being too dependent on my husband for my emotional needs. I also feel insecure and feel that he might leave me for someone else or have an affair with someone else due to my behaviour. I want to get all these out of my head.
