Would you be mad about this?

So me and my OH were getting it on, I'm almost 30 weeks pregnant so I got on top because any other positions it's uncomfortable besides doggy well I was getting winded moving all that baby around, so he flipped me into the missionary position I told him I didn't want to be in that position, reason being was he always goes hard and at that angle it hurts my back(my lower back was hurting all day) well I told him to stop because my back was killing me well he kept going until he was done . After I felt disgusting for some reason and my back was hurting more for a while after that. I mean I would have flipped in the doggy position if he would have just listened to me, I don't know I'm just venting because I felt like he didn't care about my feelings just his....
