What Should I Do If My Period Hasn't Come in 3 Months and I'm Not Pregnant?

If your period hasn't come for 3 months and you're not pregnant, it's important to speak with a healthcare provider to find out why and to keep your health on track.

Explanation

Going without your period for 3 months is a condition called amenorrhea. Even when you're not pregnant, many things can make your cycle stop. Sometimes, stress, changes in weight, or too much exercise can throw off your hormones. Your body may not have enough energy or proper hormone signals to start a new cycle. Other possible reasons include hormonal imbalances from issues like thyroid problems or conditions such as polycystic ovary syndrome (PCOS). It is important to keep track of any other symptoms you might have, like changes in your mood, sudden weight changes, or pain. A healthcare provider can check your hormone levels and overall health to see what might be causing the missed periods. They might also recommend tests like blood work or an ultrasound to look at your reproductive system. Even if you feel fine, getting a professional check-up can help you understand your body better and ensure that everything is working as it should.
