Birdmom, the book I'm reading is "Fertility, Cycles, and Nutrition" by Marily Shannon. I just read another thread recently where several people mentioned it, and it's really wonderful. I think anyone who's been ttc for awhile should read it. She links extended ewcm to low thyroid function, PCOS, and to having a sensitivity to night lighting. One other thing I noticed is that last month, when I had profuse mucus for about a week, I was taking a potent prenatal vitamin. This month, I cut my vitamin dosage in half, and my mucus has been scant. Since I just ovulated, I can't yet tell if ewcm will be prolonged. But I read somewhere that vitamins can have an impact on mucus too. I'll have to test out a few more cycles to know for sure.
She doesn't give advice specifically for the mucus, but the assumption is that dealing with the underlying problem, whether thyroid or whatever, would solve the mucus problem.
I have not ttc'd for about four years, but we are getting ready to. I've done a couple of months off and on the last little while, but I'm not getting too emotionally involved quite yet. I have a practicioner in mind whom I'm certain can help us. He's a world-reknowned naturpath, herbalist, and iridologist from New Zealand who is specializing in infertility treatment. You can check out his website at www.infertilitysolutionsinternational.com
I know him and his wife from another email list, and he is doing amazing things. He has a 75% success rate over the last four years, of not only couples conceiving, but of carrying the baby to term. His success rate for the last year or two was 89%, which is just incredible. Dh and I just need to save up the $6000 to work with him. He just emailed me all the detailed info about his program, and I have real confidence that I can conceive.
I just went to the dr last week, and my thyroid test also turned up "normal" but I'm not convinced. Unfortunately, the results were given in a voicemail message, so I couldn't ask the nurse to give me the actual numbers, but I'll be calling them to get the report.
