After ds I didn't really have to worry about it (my then fiance and I were having mega issues and I knew it wouldn't last... I ended up leaving him when ds was less than 2 months old and we hadn't had sex since before ds was born so it was never an issue). I didn't date (or have casual sex) again for years, until I met my now dh. For quite awhile we used condoms and I was on the pill. Then we stopped the condoms.... then we stopped the pill and that's how we got here ;)
We don't want any oops though. But we have no idea what to do about birth control. In theory, we'll use condoms until I can get on birth control pills again (and then we'll likely stick with the double protection for at least awhile). But what kind of pill is safe to take while breastfeeding? How soon can I start it? What other options are there for breastfeeding moms? I will not do an IUD (tried it once, had a horrible experience with it, won't do it again).
