Uncomfortable!!

I'm (apparently) 17 weeks and 5 days, which is EARLY and I'm extremely uncomfortable! At night apart from the baby kicking, I can't sleep. My gut is always tight and I can see and feel where the baby is laying at all times. During the day I feel like I'm 30weeks pregnant, have trouble walking around, can't catch my breath, have head spines, fainting, tiredness, pressure and worst I think it's making me dislike the baby (I know it's not its fault)
