Actually, before you blast Depo-Provera, I have been on it since 1991-ish- about? I rarely have periods, I have had mild spotting if anything, maybe over a year ago. I don't shop for feminine hygeine products, let's put it that way. The clinical reason for that is that your body has higher levels of progesterone & is tricked into thinking it's pregnant.
I have never had an weight gain, but I know many women feel like that was the reason. The only thing even comparably close to this convenience for me, would be a tubal ligation or a hysterectomy. But, a tubal would cause the periods to return (HELL-NO!), & the hysterectomy would decrease your sex-drive.
The reason I posted on this subject, because everyone has their own mind made up about BC anyway, is that, I am considering getting a Tubal, just to get it over with, even though I'm absolutely spoiled when it comes to NOT getting TTOTM. But recently, my DD has had a really rough time with periods, heavy, frequent, etc... I took her to a different female doctor than my own, & the doc suggested Depo before I even told her anything about my experience. Depo was approved & used in Europe with no problems about 15 years before we accepted it for this indication, ie., birth control. So it amazes me how many women refuse to take advantage of it.
Just my humble thoughts,
Marla
