Longer period..

Sarah
So my periods have been so regular for a very long time! Cause I'm on the pill. They are always 5 days long! Tuesday-Saturday
But this time my period came on tuesday night when is it usually comes during the morning. And it was super light until yesterday and then it got heavy and now its still going strong today when its meant to finish today! 😧😧 does anyone have any explanation or is that just the way it is? Keep in mind I changed pills like 6 months ago because my previous pill wasn't working as well anymore and I was getting breakthrough..this current one I'm on has been fantastic so far! This month is just out of whack :/
