Hormones and reality: listener question

Few days ago I was part of a work meeting and during that meeting I noticed how my emotions were roller coasting from totally being pissed off by the other participants to enormous self pity. A day later my period arrived a bit earlier this month and I contributed all of this emotional spinning to this fact. My question is if emotional experiences of these hormonal changes are in any connection with reality? Do they magnify some conditioning that needs to be enquiry? Or is body-mind just hijacked by these changes and updating ''Aha this is happening'' is enough?
