Has your sex life changed ?

My husband is completely weirded out by having sex because I'm pregnant. Plus I have been really sick through the whole thing. It's really worrying me. Before I got pregnant he wanted it all the time. Now he has no drive, we have sex maybe once or twice a month. He even has a hard time getting or staying hard. Even though he tells me I'm beautiful. I'm feeling fat, unattractive and extremely frustrated. Would love to hear if I'm alone in this or is this something that occurs often. He has been great with taking care of me but out intimacy and connection has faded romantically . I'm so scared!!
