Anyone still breastfeeding?

I've had horrible nausea this pregnancy. This pregnancy has been the complete opposite from my first. Anyways, I went away this weekend for the first time and didn't pump at all; day one completely sucked because my boobs were killing me but day 2 was a whole new day! No nausea at all! Still haven't had nausea or morning sickness since.. I'm totally convinced that breastfeeding is causing the morning sickness... Like there's too much going on with my body. Anyone breastfeeding and not nauseous? Just wondering if I'm making the right assumption
