There are a lot of horror stories out there about IUD insertions and after effects but there is another side to it. There are a couple of factors that make that feasible to me--one, my partner is really awesome about not trying to get out of wearing one or just withdrawing or whatnot, two, we found a condom brand we both love that never slips off and has never broken Crown, for the curious , three, we ahem, engage in other sexual activity that can't get me pregnant on a regular basis. I just want to know whether condoms are reliable enough to be our only birth control method. Good luck--it sounds like there are lots of different opinions on this one! I never had one slip or break during that time. These results are often figured via lab studies, where perfect use can be verified. As muddgirl mentioned above you're doing the wrong calculation. And I have had pregnancy scares a couple times--they never panned out but I'm not sure what the deal was, and it was nervewracking. People do it all the time. This isn't "scolding", in any sense of the word, but just a data point: I feel so so so much better, and the baby hair sprouting around my temples has proven that I wasn't mistaken about the hair loss, at least. Again, in more practical terms, that means that for people using both the pill and condoms really well over one year, that probably less than one will become pregnant as opposed to five with the pill alone or close to nine with condoms alone. So my question is - is it totally nuts to rely on condoms? I'm in a monogomous LTR, and we do hope to start trying for kids in the next three-four years, just not now. I think that people underestimate the effectiveness of condoms, and, conversely, overestimate the ease with which one can get pregnant. I tried taking antidepressants before realizing that this was just treating the symptoms instead of killing the root of the problem which I firmly believe now was the pill I was on.
