I have the worst headache I've ever felt & severe stomach pain and pain in my sides. my doctor said over the phone she assumes nothing is wrong (she's the most unhelpful, rude doctor I've ever had) should I just head to urgent care or the ER? baby is moving fine, but I'm in crippling pain at this point. thanks in advance!
