I agree with Em, the cervix symptoms for me are most helpful. The mucus readings are very reliable, but not if you’re only trained in STM. You really need to study Creighton if you’re going to rely on mucus alone. Once you add in the cervix symptom though, you don’t need to fuss so much with your temps in my experience with STM.
whatevergirl, I changed my multivit recently too, and my mucus sign is very different than it has been in previous months. It’s a healthier sign! Your vitamin can have an effect on your mucus sign, lots of things can. The change in the color of your urine is probably from B vitamins, one in particular does that, I don’t remember which one, but my multi does the same thing. If you’re due for your cycle soon, you’re not going to see much of a mucus sign right now. Your mucus sign is most prominent at the beginning of your cycle, usually the first week after you menstruate. Mine is usually heaviest around days 9-12 or about there. But some women really don’t have a prominent mucus sign. That’s why I think the cervix sign in combination is so extremely helpful.
