Thanks for giving us an opportunity to help you.
From the symptoms that you have cited, your suspicion cannot be stated as wrong. The birth control pills alter the hormonal
state of a person and can lead to these problems. What concerns me more is that these symptoms can also be cause of some disturbed liver
functions which can occur with OCPs. In that case, you should get your self checked for liver functions which can be easily done by testing your blood. At present it would be wise to discontinue the pills and seek medical attention.
Hope I am able to solve your concerns.
