I hated the pill too - I used to be on Diane and it made me throw up at 4am every 4th Sunday night like clockwork. My doctor actually said "can't you just tolerate the vomiting?" ah, no, why would I want to do that? To my mind if something makes me vomit it isn't good for me. I tried probably a dozen different kinds of pill before concluding that they all made me miserable and crazy and I wanted a break. Sangie, I totally agree about the dark cloud!
I use a diaphragm and I think its great! it's wonderful to know that your cycle is YOUR cycle KWIM? it's a little fiddly and it WILL go flying across the room in a spray of spermicide at least a few times before you figure it out! But the feeling is much better than condoms, you're in control of your own fertility, and you can combine it with NFP/ Billings so you are occasionally able to do without it (assuming you know you are not fertile and have checked the phase of the moon etc). Personally I don't use the spermicide because it didn't agree with me (and made it nearly impossible to insert) I just leave it in for 12 hours after DTD and that worked for us. We got DD on the first try so we are obviously fertile. Some doctors will try to tell you diaphragms are unreliable and push hormonal contraception on you but if you just say "well if it happened it would be a nice surprise" they usually shut up!
Good luck.
