Pregnancy and my dog

madison
So my dog is 10 months old and he's such a good boy. Although i'm 5 weeks pregnant and he keeps humping me! He is not a humper at all! He never humped as a baby and never humps now. But for some reason this week, he keeps humping me. Maybe he senses my hormones. He gets down when I tell him to but I was just wondering if anyone else had this problem ?
