Nausea after every bite I eat?

Casey
So I am 34 weeks pregnant. Yippe! Getting there! However, the past few days, I am hungry so I will eat. Afterwards, I fight getting ill every single time! I've tried eating smaller meals but it doesn't help. I've tried bland food but it doesn't help. I've tried small bland meals and no relief. I was nauseated the first 13 weeks or so and it went away. This just seems different than that. It's like period cramps over my belly and the need to vomit. I'm trying not to be overly concerned but it's getting to the point where I don't want to eat because of the fight to keep it down after. Does anyone have any ideas of what is going on? Is anyone else feeling the same? Any tips? At this point, I'm pretty desperate.
