3rd pregnancy, so different than my previous pregnancies??

This pregnancy, I love my bubble. I dont want anyone in my bubble, my SO can get closer to me than other people but not too much closer. I don't have an urge to have sex. I try so hard to try and get turned on but I cant. I'll be 9w tomorrow. Is it normal to feel this way? I love my SO with all my heart but I just can't shake off how I feel no matter what.
