Lucy Mecklenburgh has slammed a troll who said her decision to have no birth plan was "dangerous".The 28 year old, who is just weeks away from welcoming her first child with fiancé Ryan Thomas, took to Instagram on Wednesday evening to tell her 1.6million followers that she was on her way to an antenatal class. Speaking to the camera, she explained that while she's taken on the motto of "ignorance is bliss", her midwife suggested one class might be good for her.
