Is there something wrong w me?

First off, I’m pregnant with my second child. 15 weeks along. I’m not sure if being pregnant would be apart of it.

My boyfriend and I haven’t been sexually active like we used to. I don’t feel comfortable having sex with him anymore and I don’t know why. He doesn’t show me affection anymore. (Show me off, kiss my forehead, get me flowers, etc.) I feel so disconnected from him, and we’ve been having a lot of bumps throughout our relationship which I’m trying to fix. I just don’t know what to do. I want to have sex with him, I just can’t explain why I can’t. I get swollen after every time too.😞

Any advice would be appreciated.
