Try soy milk. My family switched when I was in high school due to my sister having a dairy allergy. I suggest trying chocolate to make sure you like it. Silk makes on the go sizes too :)
You don't have to drink milk when your pregnant, I know people who hate it and never drank it and they had perfectly healthy babies. They say to drink a lot of water it's way better then milk. I drank a lot of milk that's all I would drink and they told me that I should be dining water because the sugars in milk can somewhat dehydrate you if that's all you drink, same for sodas, so if your drinking water don't worry about drinking milk, you really don't have to.
