Every month, Natalie Laing would suffer through headaches, nausea and terrible cramps, hoping that she might at last be pregnant.
But every month in the four years she and husband Shane, of Te Puke in the Bay of Plenty, have been trying for a baby, her hopes have been dashed, "like a hard reality slap", and it was just another painful period.
Natalie has been diagnosed with endometriosis, a condition in which tissue like the lining of the uterus grows outside the organ. Her case is severe and it is preventing her from having a baby.
The 28-year-old Comvita saleswoman said her periods caused a "twisting and a crunching in my tummy" that left her hunched over in pain and feeling nauseous, but she had thought this was normal because she was so used to it.
Eventually she sought medical help, which led to exploratory surgery last July and she will have a second operation in several months to remove faulty tissue.
