Cycle changes on birth control ?

User Profile
Ive been on birth control since March, after having my first child, for a while my cycles where normal and only lasted 3-5 days. All of a sudden my periods are lasting 5 days and I bleed the whole time at the same pace. Why would my cycles change like that, do i need a new birth control? Should I contact my doctor?

Welcome to ehealthforum.
Changes in bleeding pattern can be of concern if they have changed to being heavier and lasting longer than 5-7 days. If you feel your bleeding has been heavy in your last few cycles, then go ahead with a hormonal check done by your gynecologist/healthcare provider. A blood work-up would reveal if bleeding is severe and resulting in anemia.
The changes in your menstrual cycles are mostly affected by the changes in hormones affecting the cycles and bleeding. Sometimes even anemia can result into heavy bleeding. You might also need a change in birth control to alternate ones or with altered dosage of hormones contained in them.
Take care.
