Hey, I feel your pain. I'm 23, newly married, and we're leaving pretty much indefinitely here in a few days. As the only girl on board, I've been racking my brain trying to think up ways to make my life easier with these things that men, damn them, don't have to worry about!
I was on oral contraceptives for quite some time with no ill effects until recently, when I started feeling psychotic for no reason. In my quest to find birth control with no side effects, I've come across an all natural kind called neem oil. They've been using it in India and the middle east for hundreds of years. Besides it's contraceptive effects, it does so many good things for you. It's been shown to help prevent yeast infections and a lot of STD's as it's an anti-fungal, anti-bacterial, anti-viral, and antioxidant. From my extensive research, India has been conducting studies on it's spermicidal qualities for years, as well as the fact that there are several products sold as a spermicide using neem oil in India.
As well as using the oil as a spermicide, you can also take Neem Leaf Tablet that they tested on married men of the Indian Army. Both you and your husband can take the pills (they're saying it could be the first male birth control pill).It takes about 6 weeks for it to get in your system, but in the 6 months of testing, they had no pregnancies. From what I understand, the failure rate is even better than oral contraceptives! I'll leave a few links for you, so you can do your own research, but as far as I can tell, and I've been researching for about 2 months now, this is the real deal. So much so, that I ordered both the Leaf capsules and the oil.
Again, I'll leave some links for you to check out:
There's a few, but if you want to do more research, just punch in neem contraceptive into Google or whatever, and you'll get loads more information. Pretty cool stuff! I hope this helped, and good luck!
