Having cramps once you're past 37 weeks may mean you're in the early stages of labour. At this stage your pregnancy has reached term, so the cramps are a normal part of your body gearing up to give birth.
Cramping, similar to normal period pain, is another common symptom after taking emergency contraception, but is only an issue if it is particularly strong. If you take Plan B, or the alternative Next Choice, less than 24 hours after unprotected sex, there is a 95% chance that you will not become pregnant.
