I am anti-condom too. DH dislikes them but its painful for me. I don't know why but it is. Its what we're doing at the moment though. I also can't use charting for TTA because I would literally have ZERO safe days.
I also feel uncomfortable with the risks associated with putting something like an IUD in my uterus. Instead, I'm thinking of getting Implanon. Its a little rod that goes in your arm and gives off progesterone (no estrogen!) for 3 years. During their efficacy trials, none of the women ovulated in the first 2 years and very few in the 3rd year (none of which became pregnant). In real life scenarios including poorly placed implants it still had a effectiveness rate better than that of sterilization. I know the whole 'poorly placed' thing freaked me out a bit but there were a lot of them being put in by people who were not trained and were just guessing on how to insert it.
There are similar side effects to that of all hormonal birth control but it is rated as safe for breastfeeding mothers and their babies. After the 3 years, they can insert a new one in the same spot the old one was if you would like to continue using Implanon.
