I've been charting for about three months now (well, three months where I actually did everything correctly!) and I've discovered that I have creamy then eggwhite cervical mucus from day 17-20(ish) and then it stops but my temps don't rise. I'm dry for about 2 days and then I get ewcm again for about 2 days and then my temps rise. Seems like a classic delayed ovulation according to TCOYF, but it seems to happen every month. Any ideas why? We've been TTC for 7 months. I travel a lot which is one of the reasons for delayed O, but it's not usually very stressful and usually quick (2-3 day) trips. Other than this delayed O, I have very textbook perfect cycles. Has anyone experienced this? Should I be talking to a doctor?
