Absolutely no interest in sex

I'm 9 weeks pregnant with my second child. I have absolutely zero interest in sex. I mean like eve thinking about it makes me sick. I'm already sick all day everyday. It's not that I don't love my husband I just have no desire. Last time I wanted it more than normal, but I also wasn't sick at all. This time has been very hard and miserable 9 weeks. Anyone else feel this way?
