My period has only been lasting 2 days

Holly

I'm pretty regular. My cycle is usually 26-28 days and my period usually lasts 6 days with a complete break on day 3, resuming regular flow on day 4. However my period has only lasted 2 full days this month and last month. It starts out normal (heavy bleeding and cramping the first day) then diminishes completely instead of starting again on day 4. Has anyone else experienced this?

I'm not complaining lol just confused. Any input is appreciated.
