Nausea at 16 weeks 4 days

Okay ladies as odd as this may sound my OB office I go to for prenatal care is pretty crappy. However they're the only ones who take my insurance within a 40 mile radius. That being said, I called them because I just now started to get nauseous and wasn't in the first trimester. No vomitting accompanying this nausea and they're saying that it isn't normal for nausea to start in the second trimester and they're concerned for the baby. The kicker? They don't want to see me in office though or check on baby or anything at all. They just had me give a urine, it came back normal, and they called it a day. I have no cramping, bleeding, vomiting, loss of symptoms, nothing. But they're concerned for the baby? Please tell me there are other who didn't have nausea until week 16 like myself and that I'm not about to suffer a third loss :(
