I started my very first patch on the 6th of December and regularly replaced the patches each week. On the first day of my third week, 20th of December, I started bleeding very lightly. The bleeding has now been going on for just over 9 days (my period usually lasts maximum 7 days). After taking off my 3rd week patch for my patch free week, the bleeding worsened significantly.

I have read that in rare cases the imbalance of hormone levels can cause heavy bleeding so as a temporary solution I have reapplied a new patch during my patch free week (29th of December).

Can anyone help and explain as for the reason(s) of this heavy bleeding and how I should go about this situation? Thank you.
