Factual error: (SPOILER ALERT) Aviva is supposed to have had a hysterectomy done on her secretly when she went in to have an abortion. She is shown waking up in the clinic, and her parents elect not to tell her, and as the movie progresses we see that she never finds out. But there are several reasons why this is impossible:
1) A hysterectomy is major surgery - the little storefront clinic Aviva is in would never have been able to perform it. She would have been transfered to a hospital.
2) Similarly, the recovery period for a hysterectomy is weeks long - Aviva would have been hospitalized for weeks, and there's no way she would not have noticed the pain she was in, or the surgical scar, or the fact that she was in a hospital. Yet in the movie she is shown walking out of the clinic the same day.
3) Even if you discount the first two reasons, Aviva would have noticed in the weeks and months afterwards that she was not getting her period, and therefore was incapable of getting pregnant. Yet we see her gamely trying to get pregnant with the trucker guy.
