Can Fostair or Spiriva affect your menstral cycle?

[Jajoma1982]

Hello. Does anyone have any experience or your asthma medication affecting your menstral cycle? My periods have gone from fairly regular, only a few days long with very little period pain to very slow, over two weeks with slow bleeding and a lot of pain. My asthma medication is the only thing that has changed. Has anyone else had a similar experience? Or is it just me? Thank you.
