Boyfriend is so insensitive.

So I'm 11weeks and 2 days and I get so tired during the day, even though I barely do anything with my time. I'm not in bed the whole day, I find things to do, but feel tired at about 2/3pm so I go to have a nap. My boyfriend says I'm "barely pregnant" and that I have no reason to be tired. Yesterday he ignored me most of the day and then went out for a meal with his younger cousin, and came back and they both started drinking. Obviously, being pregnant, I can't drink, so they both kept teasing me, and his other cousins were being so hyper and I kept snapping at them. I apologised to them and my boyfriend and said I was just emotional, and he said again that I had no reason to be emotional, and that I couldn't blame it on my pregnancy hormones because I was  "BARELY PREGNANT".
