Yeah not buying it. Though I have never played a Doctor on TV, I am aware that women can have some spotting or bleeding while pregnant, but it is not going to be the same as a normal monthly period. Maybe the baby daddy not hubby.
Well, start buying. My mother (NO shack-up pretend housemate, thank you very much) told me she had regular periods during 2 of her 5 pregnancies.
Who knows what this particular woman's story is. But honestly, who cares? The fact that it's a "news story" at all is pathetic.
