Uncomfortable w/ Hubby since Pregnancy

Okay, so I've been with my hubby for several years now and we've eachother since gradeschool .. but ever since I got pregnant I just feel .. "dirty" and uncomfortable. It's not just him, it's everything, I think my sensitive breasts make it worse, to the point where I feel disgusting even brushing against them by accident. Is this strange? Does anyone else feel this way? I'm excited for our baby and I love my hubby dearly .. I just don't understand what's going on. I'm only 12 weeks and I've felt this way since i discovered i pregnant a few weeks ago. Will i feel like this the whole pregnancy?
