Hi, I'm new to the board and desperately looking for some answers. If anyone could offer any advice I'd really appreciate it. I have 4 children - the youngest is almost 8. It's been so long since I was pregnant, I don't know if I remember the feeling or not! So I've been actively trying for a little over a year now. Normal cycle for me is 29-35 days, with my average being 31. Normally ovulate between days 15-19. My last lmp was 8th March. So for that month, I decided not to use my CBFM and try to do things more naturally. I'm now on CD 47, with no AF in sight. I've never been late. Even before charting, I kept track of my monthly cycles on a calendar, and I've never been late. My breasts are enormous and terribly sensitive and sore, I'm tired all the time, my skin looks fabulous with no acne at all, but every test is negative. My waking temps are really high - this mornings was 37.13!! Any ideas?
