I also had a copper IUD placed before I had gotten pregnant. I don't really recommend that (placement before pregnancy). It was not pleasant to have it placed... *shudder*. I hadn't even really considered it to be an option because the placement was difficult and the cramps and heavy bleeding were tough. I always had really bad cramps with my period until after I got pregnant and then didn't ever have another cramp with a period at all. But, I have only had roughly 6 periods since Dec of 2007. lol I did love the IUD though because I was off hormones and we didn't have to think about anything. My DH occasionally complained of feeling the strings, but I hear they soften up. I had the IUD removed 4 months later because we were thinking seriously about having kids by then and the cramping was hard to deal with. I wish that maybe I had done things differently, but we very successfully used NFP and occasional diaphrams for the next year before getting pregnant. I hate condoms.
My mom and grandmother have a history of fibroids so that is something that I want to research a little more before having another IUD placed especially since I have had children now. I don't know if fibroids can increase the chance of the IUD becoming imbedded/stuck/fall out.
So, it's a good thing that this thread got started, because I honestly hadn't thought about it at all. After my first baby my period came back at 12 weeks pp with exclusive nursing. I was so mad. I did chart, but my cycles were all over and hard to figure out. We got pregnant at 7 months pp. Which was a surprise to both of us! :) But, we were out of town that weekend and I knew we should have been preventing and I even told my husband but... :)
After my second, I was not excited about getting pregnant again and my DH was totally freaked out about it so I had the implanon placed at 8 weeks pp. Super easy, but I was constantly sick with some virus or other. And I mean constantly. I got cold after cold and a nasty lung infection. I would get sick and my two kids and husband never did. I never had a period though. I also had major mood issues. After about 10 months my sweet husband finally said that something had to change... The mood issues were that bad. So, again I charted and in December we decided that after the first of the year (after our 2nd son turned 1) we would stop preventing and just let God decide when the next baby would come. 5 days into the year I ovulated... and now I am due in 2 weeks!!! :)
My DH says he doesn't want any more kids after this one. I don't want to do anything permanent for at least a year. So, we did have a little discussion last night and I think we will use spermicide until my cycle starts up again and then make a decision about what we want to do, IUD, diaphram etc.
