You may have light periods, infrequent periods, or amenorrhea when breastfeeding, particularly if breastfeeding provides your baby with all or almost all of their calories. Many women believe that breastfeeding is a form of birth control, but it's not. Even if you don't have periods when you are breastfeeding, you can get pregnant. If you are not ready for another child, you should still use a contraceptive. If you think that you can't be pregnant because you have an IUD, there is a small chance that your missed period could be a sign of an ectopic pregnancy.
Ectopic pregnancy can sometimes happen due to the shape of the IUD, and you may not test positive on a pregnancy test, either. Your healthcare provider can check for it with a pelvic examination or an ultrasound. Symptoms of ectopic pregnancy include cramping in your lower abdomen, shoulder pain, weakness or dizziness, nausea, and breast tenderness.
Some women have missed periods, while others have vaginal bleeding or spotting. In addition to the use of an IUD, other factors that are associated with ectopic pregnancy include:. Ectopic pregnancy is a life-threatening condition. Seek medical attention right away if you miss your period and think you might be at risk.
Missing a period every once in a while is usually not cause for concern. That said, you should see a healthcare provider if you miss more than one period, or your missed period is accompanied by new or unusual symptoms. Seek medical attention right away if you also experience any of the following:. There are many reasons for late periods, and while most are not cause for alarm, you do need an evaluation and treatment if you have completely missed more than one period.
How your missed periods are treated depends on why you aren't having your period. The treatment can include lifestyle changes, such as diet or stress reduction, or may involve hormone replacement therapy.
Healthcare providers usually ask women when they had their last period. However, many women simply don't keep track of their period, and in some cases, they may be too busy to notice they missed a period at all. If this sounds like you, consider placing a red dot on period days in your calendar.

The egg travels through the fallopian tube, propelled in part by contractions in the fallopian tube walls. Here in the fallopian tube, the egg may be fertilized by a sperm. If the egg is fertilized, the egg and sperm unite to form a one-celled entity called a zygote. As the zygote travels down the fallopian tube toward the uterus, it begins dividing rapidly to form a cluster of cells called a blastocyst, which resembles a tiny raspberry.
When the blastocyst reaches the uterus, it implants in the lining of the uterus and pregnancy begins. If the egg isn't fertilized, it's simply reabsorbed by the body — perhaps before it even reaches the uterus.
About two weeks later, the lining of the uterus sheds through the vagina. This is known as menstruation. Mayo Clinic does not endorse companies or products.
