Thanks for writing to DoctorSpring.com with your health concern.
Some women are more sensitive to birth control than others.The symptoms do match with those of birth control .
And yes, using birth control PLUS withdrawal method PLUS condoms PLUS Plan B is overdoing it !
There is no need to use Plan B if you are on regular birth control, it just adds up side effects and negates the benefits.
Just take a break off birth control for a month, and see if it makes you feel any better.
You can then switch to another brand , with lower hormones, or a different method, if the symptoms are very bothersome.
ALl the best
Please feel free to discuss further.
PRegnancy is out of question with your regular periods, and several tests.
