Hello Anon

Thank you for writing.

You may be having a rather "off" month where you cycle is unbalanced. Causes can include hormone changes, stress, lifestyle changes. The menstrual cycle is very sensitive. You may find you get back to normal in a month or two. If you don't, your doctor can run some blood tests.
Best,
