Okay, I'm 34, a mother of 4, and a fertile myrtle. We've used NFP for to avoid and to time conception for 10 years or so. I'm pretty comfortable with my cycle and I'm pretty textbook. 5 days of flow, about 2-3 days building up to 1-2 days ECM at day 14, then start my period at day 28-30. So, now that we are Done Done and don't have that "it would be okay if we slipped up" safety net, how much risk is risky. We are okay with condoms for unsafe days, learning about withdrawl but not confident there. But really really don't want an oops right now. Phase 1ends about day 6 or 7 right? for a fertile myrtle I don't want to push that earlier phase. So if anything, withdrawl then or condoms. Then phase 2: day 7 through 4 days after peak day? Condoms. Then 4 days after peak with cross-check at cervix (and the fact that I always O at day 14?) we should be good from day 18 or so until the end of the cycle, right? Part of me says I am so regular and so textbook that this should work out great. The other part of me sees how much I can't handle a mistake and wants to take drastic measures. Does this sound risky to you? In such a basic chart, where do you put the line between risky and not so risky?
