Well if you dont want hormonal birth control you can either get the Paraguard IUD (which I dont reccommend either), you can get a diaphragm, or you can use condoms. Thats about it.

If you're looking into hormonal birth control methods, I would recommend Implanon. It's similar to the depo-provera shot, with not as many bad effects.

My wife used depo-provera for 2 years, and a few months ago we decided to switch off of it because it's supposed to cause bone density problems if used long-term. Side-effects for her were weight gain (15 pounds over 2 years, at the beginning of which she had knee surgery, and wasn't able to be physically active for months) and loss of period. It can be risky to use depo though, once you get the shot, it's basically a mega-dose of progesteron that will stay in your body for 3-6 months. Once you've got it, if you have bad side-effects, you're stuck.

Implanon uses progesteron too. Implanon is a tiny implant that gets put into your arm via a needle, they numb your arm before putting it in, and it will ache a bit for the next couple days. However it will work for 3 years before you need to take it out. Additionally, if you have any bad side-effects, or decide that you want to get pregnant again, you can have the doctor remove it. The progesteron will be completely gone from your system and you'd be fertile again within a week. With depo, if you decide you want to get pregnant, it could take over a year after you've used it for a year. My wife hasn't had any big change in side-effects since having the Implanon put in, occasionally she had an abnormal amount of moodiness for the first two weeks as she adjusted, but it didn't last long. (and I deserved it anyways :o) )

The difference with Implanon is daily micro-doses vs tri-monthly mega-doses with depo. Trials rated it at 99.9% effective too, out of 1,000 women, not one got pregnant :)

Good luck with your decision, if you decide to consider Implanon, be sure to do your research first.

I am extremely fertile. I got pregnant while on the pill and I got pregnant the same month I came off birth control twice. I didnt even have a cycle yet. Crazy !

Anyway now we are just using condoms and abstinence during fertile time. I use

to try and figure my cycle out.

Just a suggestion, I know about quite a few people who do the natural method of birth control and not one of them has had an unplanned pregnancy. You can find out more info from midwives. I know there is a large book on it too because my cousin had it and lent it to me once.
I had my IUD removed on the 11th of May and am soooooo happy. If you don't want to worry about counting days and that the copper IUD does not put hormones in your body it makes it a hostile environment and that is what prevents pregnancy. I have a few friends on that and the only thing they have is heavy bleeding during their period. Some do have bad cramps with it also.
For me the natural method has worked before, I just didn't want to have to count days so I got the mirena, but to be honest after the mirena I will never ever take any hormonal birth control again.
I have a friend who had the depo shots after one child and has never been able to get pregnant since.
