Decrease in sex drive

I'm just curious if this is normal. But I'm almost 8 weeks pregnant and I have absolutely no desire to have sex with my fiancée anymore.. I don't care to kiss him, cuddle with him, pretty much any touch from him I don't want. Same with texts when one of us is at work, I don't care to even talk to him. I was very sexual, and attention needy before I was pregnant, so it makes sense. But I wanna know if anyone else has gone through this?
