Hi A.,
I can understand your frustration with hormonal birth control and the adverse effects it has on your body. What you are describing are very common complaints among women using hormonal contraceptives. Things such as blood clots, decreased libido, increased risk of certain cancers, mood swings, etc. are all side effects. The reason many women feel decreased libido, get bloated, have mood swings, etc when on the pill is because the pill tricks a woman's body into thinking it's pregnant, thus all those symptoms are symptoms of pregnancy. And personally I believe when you're on the pill for month after month, year after year it can't be good for a woman's system to be subjected to such high levels of estrogen/progesterone for such long periods of time. It's not a natural state for a woman's body! All hormonal contraceptives subject you to this to some extent and for example on the Depo shot women can go a year or more after getting off it before their fertility returns, so yes some hormonal contraceptives can have an adverse affect on fertility.
Because a previous poster seemed to indicate that the pill seems to have more beneficial effects rather than adverse, I'd like to counter that with some additional information that many people aren't aware of. For example, the IARC (International Agency for Research on Cancer) part of WHO (World Health Organization) put out a press release in 2005 stating estrogen-progestogen oral contraceptives (OCs) were carcinogenic. They placed OCs in their their Group 1 classification, the highest classification of carcinogenicity, used only "when there is sufficient evidence of carcinogenicity in humans." Here's the link to read further: http://www.iarc.fr/en/Media-Centre/IARC-Press-Releases/Ar...
Also, another study by the Mayo clinic showed an increase in premenopausal breast cancer risk. Here's the link: http://www.mayoclinicproceedings.com/content/81/10/1290.f...
Not to mention that all the hormones in BC pills that are secreted in women's urine into our water system are wreaking major havoc on the environment (polluting the water, causing aquatic species to change sex, etc.). Here is one article: http://www.pnl.gov/news/2003/03-20.htm , but there is a lot of info on it, just search “oral contraceptives and water pollution.”
In any case, there are natural methods of spacing children based on fertility awareness. One poster mentioned NFP (Natural Family Planning) and the Couple to Couple League and that is what I use. In fact I am a certified teacher of the method and love it as it doesn’t put any artificial hormones in your body and is based on observing your own fertility signs in your own body in each particular cycle. It really does work! In any case the other poster was incorrect in that we teach both married and engaged couples, and on a case-by-case basis we will teach unmarried women as well because the information is awesome information and all women (regardless of marital situation) should learn more about how their bodies and cycles work. If you are interested, you can learn more at www.ccli.org (or just google NFP) and you can find a teacher near you or can even learn at home with their home study kit. If you’re near College Park or Bowie, we even have two classes in those locations starting up the first week of March. Please send me an email if you’re interested or want to know more about NFP.
Well sorry so long, but I hope that helps!
