• Birth control pill?

Basically, the pill has been recommended to me by a couple of doctors due to my very painful periods. My doctor suspects that this intense pain is likely a side effect of endometriosis and that taking the pill could help to reduce my pain as well as suppress the growth of more unwanted tissue. For these reasons I think that using this medication would be a good idea. However, I have concerns about how it will affect me mentally. I've done a lot of reading on this medication and a good collection of sources say that it has the potential to affect cognition and mood. These two factors are my greatest concerns as I am a college student and, admittedly, an overachiever. So, my main concern is that the pill could somehow affect my cognition in a way that might impact my studies, or that it might inhibit my ability to problem solve or my intelligence in general. Is there any likelihood of this happening?
