If you are having your periods then you are not pregnant. It is possible to have a "period" while you're pregnant (see iVillage article). Also, from experience I had light periods for all but the last three months of my pregnancy when my daughter was born.
Pregnancy
There is definetly a chance of pregnancy.
There is still a small chance you could conceive when taking birth control correctly and accuretly. Because of this, I would do a pregnancy test.
If you have missed your period for two months you may be pregnant. Take a pregnancy test to be sure. If you are not pregnant, stress may be the cause of your missed cycle.
After 8 to 10 days of your missed period. You have enough time to decide about to terminate or continue the pregnancy. It does not take months after missed period.
All home pregnancy tests*
the baby will have the chance of berth defect
If pregnancy has in fact occurred a test will show an accurate response 2 months after a missed period.
No. It could be influenced by stress, malnutrition, or sickness. Besides pregnancy.
Pregnancy is unlikely with the IUD and unlikely if you are having bleeding. Take a pregnancy test if you are still concerned.
You visit your doctor after a missed period and have a pregnancy test if you had unsafe sex,if positive then early prenatal visit is advised and good for you and the baby.
You can take a pregnancy test from two weeks after you have sex. Other than a pregnancy test or missed menstruation it can be months before seeing symptoms.
