15 weeks and feeling self consious. Is this normal?

I am 15 weeks pregnant today.

The past week or so my belly has started to slowly show. This is my first baby. I have miscarried twice before early in pregnancy.

I find clothes are not fitting me the same. My face seems bigger/ swollen. I feel uncomfortable in a lot of my clothes. I'm always tired and out of breath so quickly.

My boyfriend and I have been having some rough patches in our relationship. We just moved and are having a little financial difficulties and he wasn't really excited that I had gotten pregnant at this time. So i feel like he feels I'm unattractive. He doesn't call me beautiful anymore. He doesn't kiss me good morning or goodnight. We do have sex occasionally but it's not as frequent as before.

Is this normal feeling? How can I feel more confident in my body and all the changes going on?
