I need some serious advice.

Okay so here's the situation. My boyfriend has two boys. He has a 16 month and a 7 month old. Well we get them every weekend and we live with his parents. we found out I was pregnant a month ago. A few weekends ago I was really sick with a virus and I was contagious. I told my boyfriend that I would like to go to my house and try to get sleep and start to feel better. Well my boyfriend doesn't like that. He always says "what are you going to do when our baby is here and you're sick? Run to your parents?" I understand that it's wrong for me to just run off to my parents but I do this so I can get better with lots of rest and hot baths so that I won't have to continually "run off to my parents". Well I found out I have 3 infections with my lady parts and I've been missing a whole bunch of work because I'm so sick with a sore throat, feeling hot, headache, and bodyaches. And I told my boyfriend I would like to go home and try to feel better yet he flips out on me and says I want nothing to do with the boys! I love those boys but I need to take care of myself also! My boyfriend says (sometimes) that he can watch the boys without me and doesn't need my help yet he complains when I'm sick. He also has the help of his mom to take care of them.
Advice please?! Am I wrong for wanting to get better while I'm dealing with a lot of health issues?? I was never this sick before I got pregnant. :(
