Can you be pregnat if you get your period twice a month? i also have an iud?

Unless : Unless you have had a hysterectomy, there is always a chance of becoming pregnant. However, the odds of pregnancy are what vary. The fact that you have an iud gives you less than a 3% chance of getting pregnant after having sex. Also note that while an iud is in place, ectopic pregnancy is a concern. As far as getting a period twice a month, are you saying this happened once, or your cycle is every 14 days? Regardless, you can still get pregnant under these circumstances.
