    If you have period symptoms but no period, you might be wondering what’s going on. In this article, we’re going to explore reasons for having period symptoms without menstruating.

    Period pains but no period: Could I be pregnant?

    You've used Flo's online period calculator and know when you're due. All the  signs of PMS arrive but then... there's no sign of your period. So, what's going on? 

    Period symptoms but no period might actually be a sign of pregnancy. This is because when the embryo implants into the uterine lining, cramping may occur. Following this, breast tenderness, headaches, fatigue, and more symptoms occur as the body begins going through various changes to carry the fetus. If you suspect this might be what you’re experiencing, watch for these signs of pregnancy.

    A pregnancy test can detect pregnancy as early as 10 days after conception. But there are things that can make a positive urine home pregnancy test inaccurate, and here are some of them:

    • Not following test instructions or misinterpreting the results
    • Medications (aspirin, carbamazepine, and methadone)
    • Blood or protein in the urine

    It is also possible for a negative home urine test to be wrong:

    • Taking a test too early or checking results too quickly
    • Diluted urine (for a more accurate result, it is recommended to do the test in the morning when the concentration of hCG is highest)
    • The “hook effect,” which is something that happens when there are so many hCG molecules in the urine that they prevent the test from working properly. They are simply washed off the test, so the result will be negative.

    However, the absence of menstruation doesn’t necessarily mean you’re pregnant. There are lots of things that can cause period symptoms like cramps without actually having periods.
