Hmmm...Sundaygirl, I think it's kind of close to call. To be as conservative as possible, I'd be inclined to put your CL at 97.8, which makes it look like you didn't O until possibly cd18. Remember that you don't have to have fertile cm to O. Only temps can confirm O. Tracking cm helps you pinpoint your peak day and when you are
potentially fertile. You can O and have a thermal shift several days after your peak day. Conversely, some women have fertile cm for a few days after O. OTOH, if you discard the higher temp on cd8, you could maybe put your CL at 97.4, in which case O would've been cd13 and the low temp on cd18 is still at or above your CL. Either way, if you dtd without protection on the days you have marked, you could have a problem. Oh, and if O was cd13, that temp dip on cd18 could very well be an implant dip since implantation can occur anywhere from 5-12dpo.

I still decided condoms were our best bet.

Yeah, I think what she means by the condoms failing during your fertile time is that either that's the only time you would use them or you'd only know it failed if you got pg, which would have to happen during your fertile time. She also says that if you use a barrier method during your fertile time, your risk is only as good as the risk for that particular barrier method. She does recommend condoms as being the most effective barrier method.
As far as abstaining, it's probably a lot easier to do if you have short, regular cycles with obvious fertile times. Then you'd only have to abstain for a week at the most. With PCOS, if you were going to abstain, you might as well become celebate because of all of the potentially fertile days.
