gynecology

i am a 46 year old woman. in the last few years my menstrual cycles started getting a bit irregular but i really didnt give it much thought since i was in my forties and i knew it was just pre menopausal stuff. i would say in the last year or so i have been getting my period as follows: regular length cycle about 26to 30 days apart and then the following cycle would be about 46 days or so later then regular length then back to about 46days so that about every other month i get a double cycle.igot a period on april 7 2003 after about 46 days of not having it and it was kind of heavy but lasted only 4 days and ended rather abruptly.i did not consider it much blood since i hadnt had it in so long. now 18 days lateri got it again which doesnt usually happen but has on occasion. the blood is a light brown and very very light, in fact i hardly need a pad at all. i tend to get panicky which i hate to do and i pray my way through most things like this but i thought i would write to curezone also since i do believe in natural remedies.i have had brown blood before i think i am just wondering because i just had it on april 7. in the past when i had gone to gyn. because a period came too soon it always turned out to be hormonal. i dont really believe in doctors and i believe in thinking for myself. i have medical books and i look most things up for myself and i have found that a lot of times pharmacists will tell you stuff. even though they are not doctors they have a bit more medical knowledge than people might think and i have been able to glean some info. by listening to them at times.im pretty sure this is hormonal but i just wanted to hear what you might think and any natural remedies would be welcome.
