Thyroid conditions like hypothyroidism can lead to late and irregular periods, as can polycystic ovarian syndrome and other health issues like celiac disease. Stress can also throw your period off schedule â making you, of course, more stressed, which in turn can throw your cycle even more out of whack.
There are other causes of irregular periods including hormones, stress, STIs (sexually transmitted infections) and pregnancy. If you think a STI or pregnancy could be the cause of your irregular period, head to the doctor as soon as you can.
