Puppy and pregnancy

I recently got a husky/lab puppy. He's 11 weeks old (pretty little) im 7 weeks pregnant.  He was great and quiet. He was so gentle with me! Until i got pregnant..
Now its like he hates me! I play with him, give him treats, give him attention. Im always here! My dad and his girlfriend live here. He barks at them but thats it. With me, he bites, and hard. He only poops in my room. He bites so hard i bleed. I smack him and tell him no, but he wont stop. If im eating, he bites, jumps and barks at me, only me. But today was the worst. I was sitting on the couch and he wouldnt stop jumping, biting and barking. He made me bleed 3 times in just 20 minutes. There were other people in the room and he did nothing to them. When i moved the foot rest to where he couldnt reach me, he went to sleep. 
Why does he do this to me? Could it be the pregnancy? This is him, just to put a picture so you can see how gentle he looks.. Just not with me.
