I missed my period. I should have had it last week. Do you think I’m pregnant?

The only way to be sure of pregnancy early on is to have a pregnancy test. Pregnancy tests are accurate after a missed period — some can even detect pregnancy a few days before a missed period.

The most obvious symptom of pregnancy is a missed period. Other possible symptoms include:

  • nausea
  • inexplicable fatigue
  • sore or enlarged breasts
  • headaches
  • frequent urination

However, it is possible that any combination of these symptoms could also indicate that a woman is premenstrual, or that she has the flu or some other illness.

Many women, especially young women, have normally irregular periods. These irregularities may include missed periods and other changes in the menstrual cycle. These irregularities can vary from month to month. Although pregnancy is the most common reason for missing a period, irregularity is also caused by illness, travel, worry, or stress.
Pregnancy testing is the only way to be sure.
