Glad you found us.
Why do you need to take drugs because of BC? Well, the answer isn't so simple, and depends on many factors.
But I can tell you this, you probably need a second opinion. My advice? Get a thorough check-up from another doctor before accepting prescriptions for bc or other drugs. PMS or PMDD is often caused, or made worse, by underlying or undiagnosed medical conditions. What probably happened in your case is that your body did not respond well to the hormones/dosage in your BC. More often than not it is a road of experimentation to find the BC that fits right with you, not everyone responds the same for very many different reasons.
I encourage you to read the essay on my website (PMS & PMDD Information -- link above). Please read it in it's entirety (not just selected sections) to get a full understanding of the content. If you have any more questions, please feel free to ask.
Sincerely,
Anthea
